Andrew Riley said last week the NCAA final would probably be the last 100 meters of his season.
Riley, a senior from Jamaica better known as a hurdler, declined to rethink that idea after his stunning upset to take the 100-meter title Friday at Drake Stadium in Des Moines. He is the first Big 10 runner to win the NCAA title in the men's 100 since Willie Williams of Illinois in 1954.
An hour later, Illini freshman Ashley Spencer of Indianapolis was an upset winner in the 400 with a time of 50.95 seconds, fastest by a collegian this season. She is the first Big Ten woman to win that race at the NCAA meet.
Running into a headwind of nearly five miles per hour, Riley won in a finish so close the first three all were timed in 10.28 seconds and the next two in 10.30, forcing officials to break the times down to thousandths.
His time was 10.272, with Harry Adams of Auburn second in 10.274 and Maurice Mitchell of Florida State third in 10.277.
Riley closed with a rush to catch the leaders and won with a lean.
"I wasn't surprised," Riley said in a text message Friday night. "My coach told me once I got close to the pack I am going to win because I have the best top-end speed in the field."
Riley will be after his second NCAA 110 hurdles title Saturday, when he also is to run a leg of the 4 x 100-meter relay.
In the Wednesday semifinals, Riley had lowered his personal best to 10.02 seconds. It was just 10.40 when this outdoor season began.
He will focus on the hurdles at the Jamaican Olympic trials later this month. Riley is defending Jamaican champion in the event.
"I don't think it will be worth the risk (also to run the 100 at the Olympic trials)," Riley said. "There are 10 guys down there who can run 9.9s."
Riley's 10.02 is seventh among Jamaicans this season. That list is topped, of course, by Usain Bolt, whose best time this year is 9.76. Four others have broken 10 seconds.
The NCAA title hasn't changed Riley's plan for the Jamaican trials.
"No, I am not going to run the 100," Riley said Friday.
Spencer, a hurdler in high school, poured it on down the home stretch to run away from the field. Rebecca Alexander of LSU was second in 51.20,
She went into the race with a simple game plan: "Run. Fast."
In the women's shot, Brittany Smith of Illinois State (58 feet, 4 3/4 inches) and Jeneva McCall of Southern Illinois (57-11 3/4) finished 2-3 behind Tia Smith of Oklahoma (60-6),
That made McCall, of Thornridge High School, the second woman to win NCAA medals over her career in the shot, discus and hammer, matching Sarah Stevens of Arizona State.
McCall had won the hammer Thursday and the discus in 2010. Stevens won just one title.
Smith, a junior from Oak Park-River Forest High School, had finished second in the hammer Thursday.
