Kyle Lowry began working on his jumper immediately after the Toronto Raptors' Game 1 loss to the Miami Heat.

Lowry made a halfcourt shot at the buzzer of regulation to send the game into overtime, but he shot just 3-for-13 from the field and 1-for-7 from three-point range in the game. Lowry is shooting just 30.6 percent from the field.

Lowry began shooting baskets on the Raptors' practice court and then moved to the main court following his media availability. Lowry was in the empty arena well past midnight working on his shot.

"I have [been in a slump like this], but not at this time, so that's what's frustrating," Lowry said. "In the playoffs, all eyes are on you. It sucks to be playing this bad with all eyes on me. I know I'm better than this, so I have to pick this s--- up."

Lowry looked tentative in Game 1 and passed up shots he normally takes.

"I'm trying to get my touch back. I don't know where it's at," Lowry said. "It's kind of mind-boggling right now, and it's frustrating, but I'm not going to shy away from the criticism or anything. I know I'm not playing well at all. We got out of the first round with me not playing well, not shooting the ball well, but if we're going to get out of this next series, I have to play better, shoot the ball better and score the ball better."
