But manager Ned Yost was confident Butler will come around.
"It's not what I'm seeing from him, it's what I've seen from him in the past," Yost said. "He's a lifetime .300 hitter. He's going through a struggle for the first time.
"He got out of whack and he doesn't know why. He could always feel his swing. [Now], he's feeling things he never felt before and it's harder for him to make an adjustment right now."
Yost said that hitting coach Pedro Grifol has made an adjustment on Butler's swing which seems to have helped in Friday night's 4-0 loss.
"I saw the ball good, I felt like I put good swings on the ball and felt like I made progress," Butler said.
Maybe so. Butler had the game-winning hit in Saturday night's 1-0 victory and also hit a long drive that was caught in deep center field.
