The Rays are hoping the Japan native can turn his current slump around, one that has see him go hitless in his last 15 at-bats with seven strikeouts heading into Sunday's game.
"There might be something a little off mechanics-wise but it's certainly no excuse," Matsui said after going 0-for-4 with two strikeouts Saturday. "You just have to make the most out of the opportunities that are given to you."
Since joining Tampa Bay in late May, Matsui has yet to get going at the plate and is batting .149 on the season (14-for-94) with two homers and seven RBIs.
He maintains confidence despite the struggles from the plate and recent boos from the crowd at Tropicana Field.
"There's really not much you can do about that," Matsui said. "There's been opportunities there, and I haven't been able to make anything out of it so there's nothing wrong with the fans booing. The best thing you can do is try to make the most out of the next opportunity that comes."
Rays manager Joe Maddon said Matsui might be trying too hard. "He's not used to this kind of failure in a baseball sense because he's always been so good," Maddon said. "But you can never fault this guy's effort."
Matsui was not in the starting lineup Sunday.
