Miami, Fla. (AP) - Prince Will I Am won the $150,000 W.L. McKnight Handicap at Calder Race Course on Saturday after the race was switched to the main track because of heavy rain.

Ridden by Javier Castellano, Prince Will I Am held off Free Fighter by 2 1/2 length to win the 1 1/2-mile race in 2:38.40. Prince Will I Am paid $4.00, $2.60 and $2.10 as the favorite on the main track. Free Fighter returned $4.40 and $3.00, and Memorial Maniac paid $3.40 to show.

The field of 10 was cut in half with five scratches because of the conditions, and the race was classified as a Grade 3 stakes race instead of Grade 2.

Prince Will I Am is a 3-year-old son of Victory Gallop. He raised his earnings to $296,090 with four victories in 12 starts, finishing in the money seven times.
