Sunday final session recap

The Americans finished with 21 overall medals, tying their most from 2002 and 2014, including 11 golds. The U.S. has won all four relays at every championship since 2004. It marked the fourth time the Americans have won at least 11 golds, including a record 13 in 2004, along with 2008 and 2014.

Champion Allison (Richmond George Ranch TX), Ari Cogdell (Tennessee), Kahmari Montgomery (Missouri) and Wil London III (Baylor) rallied to win gold in the men's 4x400 relay, with London surging past Botswana in the final 100 meters to prevail by a 3:02.39 to 3:02.81 margin. Jamaica secured the bronze in 3:04.83. It marked the eighth consecutive victory for the Americans in the World 20-under final, as the U.S. last lost in the championship in 1998.

Lynna Irby (Pike IN), Anna Cockrell (Providence Day NC), Karrington Winters (Ohio State) and Samantha Watson (Rush-Henrietta NY) ran 3:29.11 to capture the gold medal for the United States in the women's 4x400 relay, with Watson anchoring in 52.45 after Irby opened in 51.29. Jamaica earned the silver in 3:31.01 and Canada, with Victoria Tachinski (Vincent Massey Collegiate), anchoring Canada to bronze in a national 20-under record 3:32.25. It marked the eighth consecutive victory for the Americans in the World 20-under final, as the U.S. last lost in the championship in 1998.

Christina Aragon (Billings Senior MT) and Alexa Efraimson (Camas WA) were both in the hunt to win the women's 1,500-meter final in the final 200 meters, before Ethiopia's Adanech Anbesa and Fantu Worku surged to sweep the top two spots in 4:08.07 and 4:08.43. Aragon became the first American female to earn a medal in the event in the World 20-under final, capturing the bronze in a personal-best 4:08.71, improving on her U.S. No. 4 all-time prep performance. Efraimson, who placed sixth in 2014 in 4:13.31, improved to fifth in 4:10.23. Ethiopia also swept the top two spots in 2014 with Dawit Seyaum and Gudaf Tsegay.

Five women, including Tia Jones (George Walton Comprehensive GA) and Alexis Duncan (DeSoto TX), broke 13 seconds in an exceptional women's 100-meter hurdles final. Elvira Herman of Belarus set the championship record of 12.85, eclipsing the mark of 12.89 set in 2014 by Georgia star Kendell Williams, with Jamaica's Rushelle Burton clocking 12.87 to secure the silver. Jones, who set the national high school record of 12.84 at the U.S. Juniors in Clovis, rallied for the bronze medal in 12.89 to become the youngest American to medal at this year's event. Duncan ran a lifetime-best 12.93, the No. 3 all-time performance by an American prep athlete, to place fourth and UTEP's Tobi Amusan, representing Nigeria, finished fifth in 12.95. Jones, who already earned gold on the women's 4x100 relay, and Duncan are two of the five U.S. prep female athletes and two of the nine American 20-under competitors to break 13 seconds.

Brian Bell (University of Houston) placed seventh in the men's 800-meter final in 1:47.68. Kenya's Kipyegon Bett and Willy Kiplimo Tarbei swept the gold and silver in 1:44.95 and 1:45.50. Morocco's Mostafa Smaili secured the bronze in 1:46.02. Kenya also took the top two spots in 2014, with Alfred Kipketer and Joshua Tiampati Masikonde, along with 2006 with David Rudisha and Jackson Kivuna, as well as 1998. Kenya has had at least one athlete on the World 20-under podium in the 800 at every championship since 1988.

Nicole Greene (North Carolina) cleared the first three heights on her opening attempt in the women's high jump final, including 6 feet (1.83m), but missed on all three tries at 6-1.25 (1.86m) and finished fifth. Michaela Hruba of Czech Republic captured the gold by clearing 6-3.25 (1.91m). Mexico's Ximena Lizbeth Esquivel cleared 6-2.25 (1.89m) for silver and Ukraine's Yuliia Levchenko cleared 6-1.25 (1.86m) to earn the bronze.

Friday evening session recap

Michael Norman (Vista Murrieta CA) ran a meet-record 20.17 to secure the men's 200-meter gold medal. It was the second straight World 20-under gold in the event for the U.S. following Trentavis Friday -- who ran a wind-aided 20.04 in 2014 -- and fifth in meet history. Norman, who clocked a state record 20.14 in the final at the U.S. Olympic Trials, secured the 100th all-time gold medal for the Americans in World 20-under competition. Norman eclipsed the 2004 championship record of 20.28 set by Italy's Andrew Howe.

Anna Cockrell (Providence Day NC) ran equal to the U.S. No. 2 all-time prep performer to capture the women's 400-meter hurdles gold medal in 55.20. Cockrell secured the second straight World 20-under gold medal in the event for the U.S. following Shamier Little in 2014 and produced the fourth title in meet history. Only Sydney McLaughlin (Union Catholic NJ) has run faster among Americans at the 20-under level than Cockrell and Leslie Maxie (Mills CA), whose national high school record 55.20 stood for 32 years until McLaughlin eclipsed the mark at New Balance Nationals Outdoor and lowered it to 54.15 at the U.S. Olympic Trials.

Darius Carbin (Mt. Pleasant CA) came through in the clutch in the men's high jump final with a lifetime-best 7-4.5 (2.25m) clearance on his third attempt to secure the silver medal. Carbin, who earned bronze at last year's World Youth final, tied the 1983 state record set by San Francisco Balboa's Maurice Crumby and equaled the U.S. No. 8 all-time prep performance. Carbin also cleared 7-3.75 (2.23m) on his third attempt to secure a medal. Gold medalist Luis Enrique Zayas of Cuba was perfect at every height through 7-5.25 (2.27m) before missing at 7-6 (2.29m). Carbin attempted 7-6 in an effort to capture gold, but was unsuccessful.

Wil London III (Baylor) produced an impressive surge in the final 50 meters to move up from fourth place and capture the silver medal in the men's 400-meter championship in a personal-best 45.27, securing the first U.S. medal in the event since 2012. Kahmari Montgomery (Missouri) was fifth in 46.48. Qatar's Abdalelah Haroun, No. 3 all-time at the World 20-under level at 44.27, delivered a convincing performance to win gold in 44.81.

Emma Fitzgerald (Thayer Academy MA) capped the women's heptathlon by running a personal-best 2:25.23 in the 800 meters for 754 points and a lifetime-best 5,577 points to place eighth overall. Kaylee Hinton (Texas Tech) ran 2:25.17 for 755 points to finish in 16th place with 5,349 points, a personal best by one point over her total from the Kansas Relays in April. The mark for Fitzgerald, who ascended from 17th place to eighth in the final two events, is U.S. No. 2 all-time by a prep athlete, trailing only the 2012 record of 5,578 by current Georgia star Kendell Williams. Austria earned its first medal at the World 20-under level with Sarah Lagger overtaking Cuba's Adriana Rodriguez in the 800 to prevail by a 5,960 to 5,925 margin, securing the gold medal.

Adam Kelly (Princeton) delivered a third-round throw of 244-0 (73.17m) to place eighth in the men's hammer final. Bobby Colantonio (Barrington RI), a high school teammate of Kelly, produced a second-round throw of 227-1 (69.23m) and finished 12th. Hungary's Bence Halasz captured the gold medal at 265-6 (80.93m).

Taylor Bennett (Baylor) placed third in the final women's 200-meter semifinal and sixth overall in 23.49 to advance to the championship. Zion Corrales-Nelson (St. Thomas More BC), representing the Philippines, was fifth in her semifinal and 19th overall in 24.05 and didn't advance.

The United States relied on an impressive anchor leg from Noah Lyles (T.C. Williams VA) to rally for third in its men's 4x100 relay semifinal in 39.70, qualifying fourth overall for the final. Amere Lattin (University of Houston), Hakim Montgomery (Troy University) and Brandon Taylor (Friendswood TX) joined Lyles on the relay.

Lynna Irby (Pike IN) ran a lifetime-best and U.S. No. 7 all-time 51.39 by a prep athlete to grab the silver medal in the women's 400-meter final in between Jamaicans Tiffany James taking gold in 51.32 and Junelle Bromfield securing bronze in 52.05.

Kiana Phelps (Kingsley-Pierson/Woodbury Central IA) placed fifth in the women's discus final with a second-round throw of 172-7 (52.60m).
