"It's all in the Collective Bargaining Agreement, he has to go on the restricted list," assistant general manager Rob Antony said. "He decided that's what he wanted to do and we support that.

The 30-year-old Mauer is hitting .324 with a .406 on-base percentage for Minnesota. Chris Herrmann and Drew Butera are filling in at catcher for the club in Mauer's absence. Designated hitter Ryan Doumit can also play the position in a pinch.

"It's totally what Joe needs to do with his family situation, that's always first," manager Ron Gardenhire said. "I stand behind him 100 percent on all his decisions and if he thinks he needs to be there, that's great. I'll never get on a person for taking care of his kids and his wife."
