Graham DeLaet’s tough. He’s a golfer. The Weyburn, Sask., native injured his left thumb during the first round of the RBC Canadian Open on Thursday, but still finished his round and expects to keep playing today. Frustrated by the injury, DeLaet was glad to shoot even-par 72 to sit eight strokes off the lead. “I was able to kind of grind away there at the end with a couple good birdies on 16 and 18,” said DeLaet, who was injured on the 12th hole and double-bogeyed No. 17. “We (tee) off tomorrow morning. As long as I feel healthy, if I can shoot 4- or 5-under, (I can) kind of just slowly kind of creep back in this tournament.” Emiliano Grillo leads the tournament at 8-under 64.
