An American spoiled the Canada Day card at Woodbine Monday when Glen Hill Farm's Bonus Pack shipped in from Churchill Downs to win the CAN$219,800 Dominion Day Stakes (Can-III).Ridden by Jesus Castanon for trainer Thomas Proctor, the Kentucky-bred son of Colonial Affair stalked the early pace set by Tails of the Crypt, Lil Personalitee and Attest. With a quarter of a mile remaining, Bonus Pack had the race in his sights. Rounding the final turn, the horse moved between rivals and moved to the front. He defeated Attest by 5 ¾ lengths, with closer Win City third.Final time for the 1 1/4 miles over a fast track was 2:03.01 as the 4-year-old posted his first stakes triumph. With the victory, Bonus Pack has won five of 19 starts, with seven placings."I had so much horse, I went for the room," said Castanon. "Once I got to the quarter pole, I got him through and he was home free. He was ready to go.""The horse had run some pretty good races but he's never run in stakes competition, and there aren't many races going this route of ground, so we came up here on Wednesday night," Proctor said of the decision to run in the Canadian race.Bonus Pack returned $9.70, $6.30, $4.60 combining with Attest ($12.50, $7.70) for a $102.80 exacta. Win City ($4.80) completed the $1,029.90 trifecta.
