CLE@MIN: Mauer rips a single to put the Twins up late

SEATTLE -- The Twins will be without their best player for a little longer, as Joe Mauer has decided to delay returning to the club after the birth of his twin girls until the team's series opener against Kansas City on Tuesday.

Since the league's rules regarding paternity leave require that Mauer return to the team on Saturday he will be placed on the restricted list and won't be paid for this weekend's games.

"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. After Sunday we will take him off because he would be available if he were playing a game [on Monday] so we will take him off after Sunday's game."

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.

Antony said that the distance from Minnesota to Seattle, did not play a factor in Mauer's decision. The Twins are fully supportive of Mauer's decision to spend time with his newborns, and his wife, Maddie.

"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."

Mastroianni, Ramirez continue steady progress

MIN@DET: Ramirez collides with Willingham in center

SEATTLE -- The Twins got a little closer to receiving some help in the outfield on Friday, as it was announced that Darin Mastroianni and Wilkin Ramirez will take another step on the road to recovering from their respective injuries.

Ramirez has been on the 7-day concussion disabled list since May 26, while Mastroianni is recovering from ankle surgery he had on May 22 to deal with a stress reaction in his left ankle that has kept him out of the lineup since April 16.

Mastroianni hit .252 in 77 games with the Twins last season, but has only appeared in eight games in the 2013 season. The 27-year-old has been in Fort Myers since July 7 and will make his first Minor League rehab start on Saturday.

"That worked kind of well because he'll probably [be the designated hitter] and play five innings tomorrow with Sunday off. Then he'll be back on Monday," assistant general manager Rob Antony said.

Ramirez will also be in Fort Myers for his rehab assignment, starting on Monday. He has hit .244 in 23 games for the Twins this year.

Worth noting

• The Twins are looking to snap a six-game losing streak at Safeco Field. Their last win in Seattle came on May 4, 2012.

• Mariners starter Felix Hernandez has not given up a run to Minnesota in 24 consecutive innings.

• The Twins' bullpen has a 1.80 ERA since the All-Star break, fourth best in the American League.
