"I'm not going to make any excuses for anything," Jay said. "I'm just playing bad right now, hitting bad right now. ... Baseball's about adjustments, and I just have to make a better adjustment right now."
Jay is batting .211 since returning from the DL. He had hit .343 in his first 27 games, and has brought his average down to .290. He said his shoulder is not a factor in his cold streak.
Jay also said his timing is not the main issue, but Matheny expressed concern with the mechanics in Jay's swing.
"He's got a swing that has a lot of moving parts to it," Matheny said. "He's also been a pretty streaky hitter, but when he's hot, he's as good as anybody. When it starts going in a bad direction, we need to spend a little extra time working hard in the cage and trying to figure out mechanically what he needs to get right again."
