EUGENE, Ore. -- Stanford junior Kori Carter won the 400-meter hurdles in a collegiate-record 53:21 seconds Friday at the NCAA outdoor track and field championships.
Carter broke the mark of 53.54 set by UCLA's Sheena Johnson at the NCAA outdoor championships in 2004. It was the fastest time in the world this season.
Carter bested rival Georganne Moline of Arizona, who finished second in 53.72 under sunny skies at Oregon's Hayward Field.
Southern California senior Reggie Wyatt won the men's 400 hurdles in 48.58, breaking his own personal best.
Oregon junior English Gardner, who was hampered by a sore right ankle and failed to qualify in the 200 the day before, powered through the women's 100 to win in 10.96, the fastest college time this season.
Gardner, also the NCAA 100 champion last year, set a Pac-12 and school record with her time. It was the third-best collegiate mark ever.
After the trouble with her ankle Thursday, Gardner admitted she was "scared out of my mind" for the 100.
"I heard the crowd so that made me thing someone was coming," Gardner said. "So that gave me a little go get `em at the end."
TCU's Charles Silmon won the men's 100 with a wind-aided 9.89. He ran a wind-aided 9.92 in the semifinals Wednesday, but Florida State junior Dentarius Locke put up a wind-legal 9.97 -- the fastest collegiate mark this season.
Oregon senior Elijah Greer won the 800 in 1:46.58, followed by Penn State senior Casimir Loxsom in 1:46.88. The title finishes an undefeated outdoor season for Greer, who also won the 800 at the indoor championships.
Southern California senior Bryson Nellum won the 400, finishing in 44.73.
Nellum redshirted his 2009 season for the Trojans after he was shot in the legs at a party by gang members who thought he was someone else. Told he might not ever reach an elite level on the track again, Nellum beat the odds and finished third at the U.S. Olympic trials in Eugene last year -- earning a spot on the team for the London Games. Nellum was part of the 1,600 relay team that won the silver medal.
Nellum also will run in the 200 final Saturday.
Dartmouth junior Abbey D'Agostino, who became the first woman ever to win both the 3,000 and 5,000 at the indoor championships, added the outdoor 5,000 title in the day's late event.
D'Agostino pulled away from Oregon senior Jordan Hasay in the final 300 meters and finished in 15:43.68.
"It's been a really exciting season," D'Agostino said. "I've learned that I can be a little more versatile than I thought."
Hasay, the most decorated track athlete in Oregon's history, wound up third and ended her college career without an outdoor title.
In other women's events, LSU senior Natoya Goule of LSU won the 800 in 2:00.06, and Illinois sophomore Ashley Spencer defended her title in the 400 in 50.28. Her mark was the best college time this season.
UTEP sophomore Anthony Rotich won the men's 3,000 steeplechase in 8:21.19.
In the field events, South Dakota junior Bethany Buell won the pole vault at 14 feet, 7 1/4 inches, San Diego State junior Shanieka Thomas took the triple jump crown with a leap of 46-4 3/4, Indiana senior Derek Drouin won the high jump by clearing 7-8 and UCLA junior Julian Wruck threw 213-1 for the discus championship.
Kansas sophomore Lindsay Vollmer won the women's heptathlon with 6,086 points, the best college total this season.
