After a phenomenal start to the 2019 USATF Outdoor Championships that included repeat titles for Lopez Lomong and Molly Huddle in the 10k, yet another U.S. title for Keturah Orji and plenty of exciting rounds action, we're ready for day two to kick off at Drake Stadium in Des Moines, Iowa.

In just three days, we'll know which athletes will represent the United States in Doha, Qatar, for the IAAF World Championships in October. But today, the men's hammer, men's shot put, men's triple jump, men's 100m, women's 100m, and the decathlon teams will be decided in finals, and rounds action will begin at 4:05 p.m. CT with the women's 100m hurdles.

4:05 p.m. | Women's 100m Hurdles, Round 1 of 3

Top 3 each heat + next 4 fastest to 2 semis; Top 4 each semi to final

Similar to what the short sprinters faced yesterday on the straightaway, a -2.5 headwind awaits the first-round competitors of the women's 100m hurdles—the strongest event for the United States in terms of overall depth and talent of the field.

In the first heat, Christina Clemons ran a very controlled, smooth 12.77 to claim the top automatic-qualifying spot. USC's Chanel Brissett followed with a 13.01, with Gabriele Cunningham taking third in 13.04.

Heat two followed with Nia Ali, who helped the U.S. sweep the medals in this event at the 2016 Olympic Games with a silver medal alongside gold medal-winner Brianna (Rollins) McNeal and bronze medalist Kristi Castlin—both of whom are in heat three. Ali crossed the line first in 12.92, overpowering a possible challenge from Tonea Marshall of LSU, who finished runner-up in 13.10. Tiara McMinn of the University of Miami came up third with a time of 13.25.

The third heat was called back, and was initially given a green card, but then the officials started taking a closer look at the film, and the anxiety surely must've started creeping in... but, fortunately, they upheld the original conclusion, and called the athletes to their marks again. The hot heat, led by McNeal in 12.75, Queen (Harrison) Quedith Claye in 12.79, and Tiffani McReynolds in 12.95, displaced Castlin from the automatic qualifying spots in fourth.

Keni Harrison, the world record holder with a PR of 12.20, is the cornerstone to the United States' hurdle prowess, and she headlines heat four. Into a -3.7 headwind, Harrison ran 12.91. Sharika Nelvis, the American record holder in the 60m hurdles, pulled up five meters shy of the line once she was confident she locked in her spot and finished runner-up in 13.22. Despite a very delayed reaction to the gun, Arkansas phenom-turned-Asics pro Payton Chadwick grabbed the last big Q in 13.58.

4:30 p.m. | Men's 1500m, Round 1 of 2

Top 3 each heat + next 3 fastest to final

From the gun in heat one, Kyle Merber raced like he wasn't recently recovering from injuries and took the field out hard through the first lap in 57.84. The next lap slowed a bit, 60.87, but the order didn't change as Merber continued to lead Izaic Yorks, Rob Napolitano, and the towering figure of Johnny Gregorek—the second-fastest American to ever run the mile after his 3:49 indoors, though his recent performances haven't been indicative of that lately. At the bell lap, Yorks took over, but Josh Thompson of the Bowerman Track Club had the stronger finish and got there first in 3:42.12 to the Brooks Beast's 3:42.28 and Gregorek's third-place 3:42.44. Despite Merber's earnest attempt to make it a race, he didn't quite have the fitness to sustain his early efforts and ended up second-last in 3:48.87.

Heat two, featuring the ebullient, mulleted Craig Engels, went out with a pedestrian, 61-second first lap. Engels held his spot in the middle on the outside in lane two, right next to Brooks Beast Henry Wynne. At 800m, they were rolling through in 2:04, ensuring the heat would be left to a kick. Predictably, with a lap to go, Engels and the rest of the group, then led by Mac Fleet, took off. Henry Wynne assumed the lead with 200 meters to go, followed by Engels. Swinging wide and repeatedly looking over his shoulder, the Nike Oregon Project athlete finished side-by-side with Wynne with a slight edge for the win, 3:43.22 to 3:43.23. The Mission AC's Eric Avila took the third automatic spot in 3:43.43.

2016 Olympic champion and defending U.S. champion Matt Centrowitz, making his first appearance at a U.S. championships in a red Bowerman Track Club kit, contested heat three against primary foe Ben Blankenship. Although Lopez Lomong said he would show up on the line of the men's 1500m today after repeating as U.S. 10k champion and running the IAAF standard, his imposing figure was nowhere to be found. Multiple-time Division II 1500m champion David Ribich took the field through lap one in 61 seconds with Blankenship and Centrowitz in tow. At 800m, former Oregon Duck and current adidas pro Sam Prakel moved up to tail Blankenship. At the bell, Centrowitz began to wind things up and drifted onto the shoulder of Prakel. He kept Prakel and Blankenship in his sights as he drafted behind them into the homestretch, gapping the rest of the field by 10 meters. Blankenship took that one in 3:43.07, then Prakel in 3:43.14, and Centrowitz in 3:43.46.

4:57 p.m. | Women's 3000m Steeplechase, Round 1 of 2

Top 5 each heat + next 4 fastest to final

Courtney Frerichs, the American record-holder in this event, owns top billing in heat one. It will be interesting to see how Allie Ostrander, the three-time NCAA champion, fares this weekend in her Brooks Beasts debut—can she come up with a big PR? Could she make the team after such a long year of NCAA XC, indoor and outdoor competition? Courtney Frerichs allowed Katy Kunc of HOKA NJNYTC to lead and tucked in comfortably behind her and Ostrander. They occasionally traded leads throughout the race, which started off at 79-/80-second pace for the first three laps and then dialed up on lap five, when they transitioned to 66s. At that point, Frerichs and Ostrander dropped Kunc and continued to lope along without strain. Ostrander seemed intent on keeping Frerichs out of the lead—during the second-to-last water jump, Frerichs, a much more skilled water jumper, overtook her slightly, and Ostrander fought to make up the ground on the inside and maintain her position. At the bell lap, which rang at 8:31, Frerichs and Ostrander had built a 20-meter gap ahead of Oiselle's Marie Lawrence. Frerichs made her move at the last water jump, where she struck out and put several meters between herself and Ostrander, and then glided to the win in 9:46.35 to Ostrander's 9:47.54. Lawrence, Oiselle's Alex Wilson, and Kunc obtained the next three automatic spots.

In heat two, U.S. juggernauts Emma Coburn, 2016 Olympic bronze medalist and 2017 world champion, and 2016 Olympian Colleen Quigley will likely emulate what we saw between Frerichs and Ostrander in heat one. Coburn earned a bye for winning the world title two years ago, so the U.S. has an extra spot to award for the team. Ostrander seems to be the most well-positioned for the third spot, but we'll have to see if anyone else can get in the conversation with a standard on Sunday. With two laps to go, Coburn and Quigley put 10 meters in front of Marisa Howard in third. In calm, controlled efforts for both runners, Coburn won in 9:51.43 to Quigley's 9:53.48.

5:48 p.m. | Women's 100m Semifinal

Top 3 + next 4 fastest to 2 semis; Top 4 each semi to final

Finally, our first semifinal—now things are about to get interesting. 

Into a -1.6 wind, newly minted Nike athlete Teahna Daniels continued her terrific post-collegiate progression with a heat one win in 11.20 (11.191), followed by Morolake Akinosun, who beat her out of the blocks but nearly tied her at the line in 11.20 (11.199), which equaled her season's best. 2019 NCAA champion Sha'Carri Richardson grabbed third in 11.28 just ahead of USC's Twanisha Terry in 11.30, who made it in on time.. First-year Nike pro Kayla White finished fifth, and it doesn't look like her 11.39 will be able to help her get in on time.

Jenna Prandini, who looked terrific during her first-round win yesterday, is a no-show in heat two. Into a -2.4 wind, English Gardner rocketed out to a great start along with Dezerea Bryant, and they went 1-2 with the two fastest times of the day: 11.16, a season's best, and 11.23. Aleia Hobbs nabbed third in 11.31, followed by Arkansas State's Caitland Smith, who ran 11.32 and time-qualified.

Noteworthy names who did not advance to the final include White, Ashley Henderson, Mikiah Brisco, and Candace Hill.

6:02 p.m. | Men's 100m Semifinal

Top 3 + next 4 fastest to 2 semis; Top 4 each semi to final

It's time to see how healthy Ronnie Baker truly is. Last year's second-fastest man on the planet opened up his season here at the championships, and he looked fit and fast. Today, it was more of the same—a great start, a terrific middle, and an easy, coasting finish for a 10.28 win makes it seem like he could be getting back to his speedy ways this weekend. Perennial Team USA member Mike Rodgers finished runner-up in 10.32, and 2019 NCAA 100m and 200m runner-up Cravon Gillespie took third in 10.36. Christopher Belcher's 10.39 will get him into the final, as well. 

World leader Christian Coleman, who surely must be eager to reclaim the U.S. title after his rival, Noah Lyles, won it last year, took the second heat from Justin Gatlin, who's having quite the season and has remerged as a true world medal contender this year. Coleman shot out of lane five and once again shut it down early, crossing the line in 9.96 and looking like he's in a class of his own. Isiah Young earned second in 10.15 with Gatlin right behind him in 10.16. Ameer Webb also got into the final on time in 10.26. 

6:18 p.m. | Women's 800m Semifinal

Top 3 each heat + next 4 fastest to 2 semis; Top 3 each semi + next 2 fastest to final

Heat one definitely boasts the stronger field, as Ajee Wilson, one of the fastest women in the world, headlines. Olivia Baker, the former Stanford standout, took the field out in 60.82, and Wilson sat on her shoulder until they had 400 meters to go. Hanna Green made a move to match Wilson with 300 meters to go, and 17-year-old Athing Mu went after her. Those three finished in that order with the following times, respectively: 2:01.02, 2:01.37, 2:02.47. Baker took fourth in 2:03.15 for a spot in the final.

Raevyn Rogers owns the quickest PR, 1:57.69, and season's best, 1:58.65, in heat two. If Ce'Aira Brown didn't lose too much speed during her season that primarily consisted of cross-training, she could make it into the final. It will be interesting to see how Sammy Watson runs here, too—she left Texas A&M to go pro in the middle of the indoor season. Rogers got out authoritatively with a 59.03 lap—in Monaco, she lamented about getting into trouble early in the race, and said she didn't want to make the same mistake again. She cleared the field early yesterday, and she did the same again today all the way to the line, finishing in 2:00.90—the fastest time of the evening. Brown was on her heels with 300 meters to go, but apparently lost some closing stamina due to injury. Penn's Nia Akins cruised past Brown, and then Rebecca Mehra caught Akins at the line in 2:02.86. Brown could've possibly made it into the final, but eased up at the line, and Watson closed hard to edge her out, 2:03.23 to 2:03.26.

In his trademark racing style, Erik Sowinski bolted to the front immediately and led from the break, taking the field through the first lap in 51.46. With 300 meters to go, Brannon Kidder scooted past Sowinski, followed by Clayton Murphy, then Harun Abda, and Isaiah Harris in a late surge. Murphy won in 1:45.24 with a 52.96 final lap; Kidder finished runner-up in 1:45.42, and Isaiah Harris got third in a season's best of 1:46.05—he still hasn't run the world championships standard of 1:45.80. Sowinski faded to sixth on the homestretch in 1:46.84; he'll miss his first U.S. final since 2011. Abda will make it in on time with a season's best of 1:46.37, along with Robert Downs, who ran a 1:46.46 PR.

In heat two, Bryce Hoppel's 21-0 win streak will be in serious jeopardy as he faces off against Donovan Brazier. He led up until the final 300 meters, when Brazier overtook him and gapped him by five meters heading into the straightaway. He won with negative splits, 55.16 and 52.11, as he halted Hoppel's fairytale undefeated season, though the Jayhawk will see him again in the final. Brazier won in 1:47.27, Hoppel took second in 1:47.84, and Isaiah Jewett ran 1:48.29 for third.

Top 3 each heat + next 4 fastest to 2 semis; Top 4 each semi to final

In heat one, 30-year-old Jessica Beard faced off against a host of collegians and recent graduates, but ended up qualifying ahead of one of the most promising talents of the group, Lynna Irby, who faltered heading into the homestretch and fell to fifth behind fourth-place Briyahna DesRosiers of Oregon (52.02, Q) and third-place Beard (51.89). Despite the gusty conditions, Kendall Ellis and Wadeline Jonathas ran some pretty quick times, delivering 50.81s and finishing 1-2, respectively.

Regardless of what Allyson Felix did in the semifinal, the fact that she was even able to compete at such a high level less than a year after going through a high-risk pregnancy that required an emergency C-section is absolutely remarkable. As if she couldn't get any more impressive, she not only made it to the line in the preliminary round, she qualified through to today's semifinal in 52.20. To mere mortals, that's ridiculously fast, but to Felix, that's far from her potential—she owns a 49.26 400m PR, and who could ever forget her legendary 47.7 split in 2015? BUT OF COURSE, SHE QUALIFIED FOR THE FINAL, AND HER LEGEND SOMEHOW GROWS FURTHER. Felix finished third in 51.45! Shakima Wimbley took the top spot in 50.20, followed by Courtney Okolo in 50.94. Jasmine Blocker, fourth, made it in with 51.58. 

Allyson. Felix. 

Unbelievable.

Double amputee Blake Leeper stole the show in heat one with a dominant 44.38 win, which was also a lifetime best and the fifth-fastest in the world this year. He hasn't been cleared yet by the IAAF to compete in the world championships in Doha, but they should probably get on that now... he might be a contender to make the team. Michael Cherry finished runner-up in 44.85, then North Carolina A&T's Trevor Stewart in 45.16, and adidas's Tyrell Richard in 45.21. Fred Kerley's brother, Mylik Kerley, finished just outside qualifying in 45.26.

Stormin' Michael Norman did his thing in heat two, but not without fierce competition from Fred Kerley. The two finished neck-and-neck, 44.04 to 44.09, as Nathan Strother trailed in third (44.69), followed by Vernon Norwood (44.81). Norman's strength and resolution were apparent when he added power to the final two strides to beat Kerley exactly when he wanted to—right before the line.

#HTownSpeedCity! Amere Lattin claimed heat one in 49.12 over the runner-up, former Illinois star David Kendziera (49.21), and third-placer Norman Grimes of Texas Tech (49.43). Team USA stalwart Kerron Clement, who took fourth in 49.83, will also appear in the final.

Rai Benjamin made 48.30 look like a walk in the park as he claimed heat two. Unfortunately for Johnny Dutch, he missed out on making the final.

7:44 p.m. | Women's 100m Final

She didn't win the Division I NCAA title—didn't even make it onto the podium in fourth—but today, after a wonderful post-collegiate campaign that included a NACAC U23 title and a third-place showing in a loaded Monaco 200m, Teahna Daniels won the U.S. 100m title in 11.20. The 27-year-old English Gardner also found redemption in her finish today, taking runner-up honors in 11.25. Morolake Akinosun, who raced brilliantly through the rounds (as did Dezerea Bryant), caught Bryant at the line for third in 11.28. Sha'Carri Richardson, who blew the minds of so many in Austin, Texas, when she ran 10.75 to reset the collegiate record, ran almost a full second slower today to finish last in the final. The wind reading was recorded at -1.7.

7:53 p.m. | Men's 100m Final

Mike Rodgers makes teams.

I find his runner-up finish far more interesting than Christian Coleman's continued dominance of the 100m (he won in 9.99, -1.0 wind), though it was his first U.S. title in the event. 

Today, with a result of 10.12, the 34-year old Rodgers qualified for yet another world team. He and Coleman will be joined by Christopher Belcher, who narrowly finished behind Rodgers, 10.114 to 10.120.

Justin Gatlin opted not to show for the final, as he has the bye for winning the 2017 world title.

Men's Hammer Throw Final

On his final toss, Conor McCullough turned the lead he had on the rest of the field into a chasm with a gargantuan 78.14m/256-4 effort that reset his lifetime best and broke the facility record at Drake Stadium, the site of so many U.S. championships. The next-closest competitor, Rudy Winkler, was nearly two meters from that mark (76.51m/251-0). Kennesaw State's Daniel Haugh threw a PR, 76.44m/250-9) to land on the podium. As all three competitors have the IAAF standard, they are your team heading to Doha.

Men's Triple Jump Final

Without 2017 world champion Christian Taylor, who has the bye into Doha, in the mix, this event seemed to be Will Claye's for the taking. But Donald Scott managed to crash the party in a major way as the unattached athlete beat Claye with his very first jump, which recorded a fantastic 17.74m mark. Claye, who earlier this year produced the third-best triple jump in history with an 18.14m result, could only respond with a best effort of 17.70m on his third jump. Your 2019 world team:

Men's Shot Put Final

Ryan Crouser left his mark on Drake Stadium with a 22.62m toss that broke the facility record and claimed him another U.S. title. The reliable Joe Kovacs came through in second with a season's best throw, 22.31m, followed by Darrell Hill, who put the shot out at 22.11m—a season's best. They are all going to Doha to represent Team USA.
