Track and field Also an excellent track athlete, Carroll ran a 10.30
non-wind-aided clocking in the
100 metres at the Del Rey League finals in May 2009. It was the fastest by an American high school sprinter in 2009, and tied
Quincy Watts and
Riley Washington for the third fastest ever by a California high schooler, behind only
Henry Thomas and
Ricky Carrigan. In June 2009, he won the CIF state track titles in the 100 (10.38) and 200 (21.08) for the second consecutive year, becoming the first athlete to do so since
Charlie Paddock in 1917 and 1918. His achievements earned him a 2009 All-USA track and field team selection by
USA Today as well.
