The former Texas City High School star won the 100-meter dash in the 17-18 year-old division on Sunday at the United States Track and Field Junior Olympics in Walnut, Calif.
Prevost was part of the Carl Lewis Athletic Stars 400-meter relay team that won the title at the 2006 Junior Olympics. That team, again anchored by Prevost, and including his brother, Lee, and Ball High senior Terrell McNeil, finished fourth on Saturday.
The Baylor University-bound Prevost blitzed the field in Sunday’s 100 dash final. He finished in 10.49 seconds. The runner-up was 0.15 second behind.
Prevost finished fourth in the 200 dash, in 21.15.
He won both events at the UIL Class 4A state track meet in Austin in May and also won the long jump.
McNeil registered the fastest times in the 200 and 100 preliminaries on Thursday and Friday but did not compete in the finals on Saturday and Sunday.
Texas City resident Lauryn Caldwell, representing the Mainland Jaguars, turned in three top-five finishes in the 11-12-year old field events. It was her third straight trip to the Junior Olympics.
Caldwell finished third in the discus with a mark of 94 feet, 6 inches, 12 feet behind the winner. She finished third in the javelin, with a mark of 103 feet, which was 21 feet behind the winner.
And she finished fifth in the shot put with a toss of 34 feet, 91?2 inches, 4 feet 6 inches behind the winner.
