"It's a lot better," Ackley said before the series opener. "I probably could have played Sunday, but it was one of those situations where we had the next day off and they wanted to give me that extra day to try to get better.
"It's not 100 percent. I still feel it a little bit, but I can play with it. And if I can play, I'm going out there."
Before sitting out the weekend, Ackley was tied with Kyle Seager for the most games played on the team at 144. He still leads the club in at-bats with 571 in his first full season in the Majors. He's not sure whether that long haul is catching up with him, but he wants to finish the season strong.
"I don't know if it was from all the innings from all those games we'd played previously or if that had anything to do with it or what, but I felt it right when I woke up [Friday]," he said. "I probably slept on it wrong, plus all those innings we'd just played. You never know. But I'm ready to go now."
