World 100-meter champion Yohan Blake ran the year's second-fastest time on Wednesday, winning the Cayman Invitational in 9.84 seconds.
Only Usain Bolt, Blake's training partner in their home country of Jamaica, has run faster this year. Bolt won a meet in Kingston in 9.82 on Saturday.
Blake won last year's 100 at world championships after Bolt was disqualified for a false start. The two aren't expected to square off in the 100 until Jamaica's Olympic trials at the end of June.
On Wednesday, Blake defeated another Jamaican, Michael Frater, who finished in 10.05 seconds. Keston Bledman of Trinidad and Tobago finished third in 10.06.
In the women's 100, American world champion Carmelita Jeter won in 11.04 seconds, beating Jeneba Tarmoh by 0.09 seconds.
