Friday's Pan American Junior Championship Action

* Correction: A previous version had Jamal Walton's age at 19-years-old. He turns 19 in November, according to the IAAF, and is heading into this 19 age year for the Pan American Junior Championships. 

The Pan American Junior Championships (U20) are here and Milesplit is going to break down what's happening in Trujillo, Peru, as it comes to us. 

Men's 10K Racewalk

All right, so Ecuadorian Alexander Hurtado Espinos, 18, wins in 40:37.64. In seventh for a medal is Cameron Haught, 19, of the United States, who finishes in 47:44.72. This event is heavy on DQ's, we have three of them. American Eduardo Uria, 18, is unfortunately one of them. 

100m Men's Decathlon

The first event of the men's decathlon is over and it was a close battle between two heats, with Aaron Worrell, 19, of Barbados taking the overall top time in 10.84 seconds for 897 points. Jordan Santos de Souza, 19, of Brazil, is second in 10.98 seconds for 865 points. We had two from the United States, including high school junior Kyle Garland, 17, who ran 11.33 seconds for 679 points. American George Patrick, 19, ran 11.16 seconds for 825 seconds. 

Women's 100m Dash Semifinals

Woah, Woah, Woahhhhhhhh. I had to get this verified, because it's wrong, but results have two women running 10.77 seconds (Barbados' Tristan Evelyn) and our very own Symone Mason going 10.79 seconds. That would have been a new national record, a senior class record and an 18-year-old record. It's wrong. Todd Grasley of is telling me Evelyn and Mason went 11.77 and 11.79. Still, Mason is through to the next round with the fifth best time in the preliminaries. Trinidad & Tobago runner and St. Thomas Aquinas (Fl.) graduate Khalifa St. Fort, 19, ran the overall fastest time of the preliminaries in 11.64 seconds. American Rebekah Smith, 19, was one of two women who ran 11.75 seconds. She's through as well. 

Men's 100m Dash Semifinals

Our guy Maxwell Willis, 19, a recent freshman at Baylor, ran the overall best time in the preliminaries with a 10.48 second qualifier. American Tarrik Brock, 19, runs 10.50 seconds along with one other sprinter to qualify as well. 

Men's Hammer Throw

We have our first Pan American Junior Champion! That's Joshua Hernandez, 19, who threw a mark of 72.55 meters. Hernandez, who's from El Paso, attends Sam Houston State. Cameron Thompson, 19, was fourth with a throw of 66.84 meters. 

Women's 100m Hurdles Semifinal

The preliminaries were dominated by Americans Tara Davis, 18, and Tia Jones, 17. Jones, the high school sophomore from Marietta, Georgia, ran the overall fastest time of 13.23 seconds, while Davis, a recent Agoura (Ca.) High graduate and University of Georgia signee, was second in 13.42. Expect both of these women to produce some big results in the final. 

Men's 110m Hurdles Semifinal

Recent Northeast (Fl.) High graduate Damion Thomas, running for Jamaica, threw down the fastest semifinal performance with a time of 13.51 seconds. Americans Eric Edwards, 17, a high school junior for Langham Creek in Texas, had the second fastest time at 13.62, and Joseph Anderson, the University of Oregon signee and CIF champion in the 110m hurdles, was third in 13.66. 

Women's 400m Semifinal

A pretty comfortable effort from Cuba's Roxana Gomez Calderon, 18, who won the second heat and was the fastest semifinal runner in a time of 52.55 seconds. In the first heat, American and Texas A & M University athlete Jaevin Reed, 19, had the second best time of 52.76 and qualifies for the final while fellow US'er Takyera Roberson, 19, of the University of Alabama, also pushes through with a time of 53.79. 

Men's 1500m Semifinal

This can best be described as a tale of two heats! Huge surges were necessary in Section 1 as eight of the 10 competitors ran qualifying times at 4:00.69 or faster. That included the overall fastest competitor of the day in Colombian Carlos Hernandez Samaca, 19, who posted a stellar 3:51.59, though University of Connecticut freshman Eric Van Der Els was right behind him in 3:52.19. In Heat 2, recent St. Joseph Notre Dame (Ca.) High graduate Cooper Teare paced the field smartly to win in 3:57.25 as he moved ahead to round two. Canada's Kyle Madden was second in 3:56.27, and only four in Heat 2 ended up moving on to the finals.

Results not available. 

Men's 400m Semifinal

A loaded field held strong and we'll have some big names in the finals here. Leading all runners across three heats was Miramar (Fl.) High junior Jamal Walton, 18, of the Cayman Islands, who ran 46.17 seconds. American Josephus Lyles, a pro running for adidas, was first out of the second heat in 46.32 seconds, while Chantz Sawyers, a graduate of High Point Christian Academy and future University of Florida athlete, was second in 46.9 seconds. In the third heat, Californian Zachary Shinnick, a CIF champion headed to the University of Southern California, was first in 46.69 seconds. 

The finals should be a thriller. 

Shot Put Men's Decathlon

The Americans are on top for the shot put. Patrick hauled in a nice throw of 14.59 meters, while Garland was just behind Patrick in second for a mark of 14.26 meters. Patrick logged 765 points, while Garland posted 744 points.

Women's 100m Hurdles FINAL

And we have our winner. Earning her first Pan American Junior Championship title -- she will have another shot in 2019, if she chooses to come back vs. USA Seniors -- Georgia's Tia Jones wins in a Pan American Junior and sophomore class record of 13.01 seconds -- she lowered her own sophomore class mark -- over Tara Davis' 13.05. Like we suspected, it came down to the two Americans. The dominant Davis, who ran an all conditions 12.83 winning time at the CIF Championships, was just behind the revving-Jones, who's competing in just her fourth event this season. Hey, never too late to make a big statement, right? 

Men's 100m Hurdles FINAL

Eric Edwards, the rising high school senior from Langham Creek (Tx.) High, will have a nice story to tell his friends when he heads back to school in the fall. Because he won a Pan American Junior Championship! He ran the second best time of his career in 13.33! Heyy ooo. Edwards, who grabbed a junior class record at USA Juniors with a 13.32 (-1.8), comes back with a 13.33 (-0.6) over Canada's Ansatasios Eliopoulous, who finished in 13.36. Californian Joseph Anderson, 19, was third in 13.43 seconds. Edwards, 17, continues to crush the postseason. He won a UIL state title (13.39), a TTFCA Meet of Champions title (13.47), a Great Southwest Classic title (13.45) and was second at New Balance Nationals Outdoor (13.54) before winning USA Juniors in a PB. 

Women's Shot Put FINAL

BOOM SHOCKA-LOCKA. Our national record holder, Donovan Catholic (NJ) High graduate Alyssa Wilson, takes gold in 17.70 meters, a 58 foot, 1 inch throw, and bests her own national record of 57-1.25. She also wins over Maria Orozco Castro of Mexico (16.57m) and fellow American Samantha Noening, 19, a native of Wisconsin and Arizona State University freshman. This is undoubtedly Wilson's biggest win of her career and comes right before she enrolls for her freshman season at UCLA. A great performance to cap off her career in high school, all while wearing the TEAM USA uniform. 

Women's 400m FINAL

Cuba's Roxana Gomez Calderon wins in 51.46 seconds, just edging the US's Jaevin Reed (51.71) at the finish. Canada's Kyra Constantine was third in 52.63 and the US's Takyera Roberson was fourth in 52.89 seconds.

Men's 400m FINAL

How about it! Miramar (Fl.) High rising senior and Cayman Islands star Jamal Walton became the second high schooler to go under 45 seconds, winning a Pan American Junior Championship in 44.99 seconds. Dannnnnnggggg. Walton and the US's Josephus Lyles were battling it out in the last 50 meters, but Lyles was unable to make up the difference and finished second in 45.3 seconds. American Zach Shinnick, who's coming off a CIF championship, finished third in 45.98 seconds, his second straight outing under 46 seconds. 

Women's 800m Semifinal

A balanced heat in Section 1 of 800m, with five athletes going 2:12, including the US's Laurie Barton, a Virginia Tech University freshman, who finished second and qualified for the finals. But in Heat 2, everyone went bonkers. The top four runners went sub-2:09, including Florida native Caitlin Collier, who finished with the second in 2:07.13 and locked herself into the final. Colombia's Johana Arrieta Madera was the fastest overall athlete at 2:06.23. Collier has the ability to bump it up in the final. Her career PB is 2:03.32. 

Men's 800m Semifinal

Measured performances from both of the Americans. Terrell Jackson, 19, was third in the first heat in 1:50.25, while Oak Park (MI) High grad Cameron Cooper, who's headed to LSU, was first in Section 2 in 1:50.00. Cooper had the third fastest run in the semifinals. Puerto Rico's Ryan Sanchez Estrada was the fastest athlete at 1:48.82. Should be an exciting final -- that takes place tomorrow at 10:15 a.m. CT.

Men's 100m FINALS

University of Southern California freshman Tarrik Brock, who finished second at USA Juniors to Maxwell Willis, won the Pan American Junior Championships on Friday with a time of 10.45 seconds. After a gun misfire, the field came out of the gates a second time and it was Brock who flushed toward the finish. Meanwhile, it was a forgettable race for Baylor freshman Maxwell Willis, who finished first in the preliminaries with a time of 10.48 seconds. He was eighth in 10.77 seconds. Brock's PB is 10.16 seconds at the NCAA Division I West Preliminary.
