SEATTLE -- The Mariners made a trio of roster transactions Friday.
Maurer (1-4, 7.52 ERA) lasted at least five innings only twice in seven Major League starts after injuries to James Paxton, Taijuan Walker, Blake Beavan and Erasmo Ramirez's performance forced him into the starting rotation.
Manager Lloyd McClendon said Maurer underwent an MRI on Friday after complaining of back soreness following last night's start. But the fact the 23-year-old was demoted and not placed on the disabled list indicates he's healthy because a club isn't allowed to option an injured player to the Minor Leagues.
To help fill Maurer's roster spot, the Mariners recalled outfielder Endy Chavez from Triple-A Tacoma and put him in the leadoff spot while rookie James Jones was moved down to No. 2. In 37 games this season with the Rainiers, Chavez posted a .272/.289/.346 slash line with two doubles and no home runs. A 12-year MLB veteran, Chavez played for the Mariners in 2009 and 2013.
Meanwhile, Seattle placed Beavan on the 60-day disabled list. The right-hander had been on the 15-day disabled list since mid-April with tendinitis in his right shoulder.
Cano out of the lineup with minor hand injury
SEATTLE -- Mariners second baseman Robinson Cano was out of the lineup with a minor hand injury for Friday's series opener against the Tigers after he was a late scratch (sick) prior to Thursday's 7-5 loss to the Angels.
"Robbie's still not feeling well and he also has a minor hand contusion," manager Lloyd McClendon said. "I'm just going to leave him out. He's going to be day to day. He's not going to be in the lineup today. We'll see how he's feeling tomorrow."
Cano, who the Mariners signed to a 10-year, $240 million contract last offseason, played in Seattle's first 52 games before sitting out Thursday. Cano isn't expected to miss more than a few games.
"I feel better than I felt yesterday," he said to a team spokesman.
Cano wasn't available to speak directly with the media prior to Friday's first pitch because he was getting treatment, but McClendon intimated that his No. 3 hitter's hand injury came from swinging a bat.
"It's nothing serious. He has a little soreness in the muscle area," McClendon said.
Entering Friday, Cano had played in 1,172 out of a possible 1,187 games since 2007, most in the Major Leagues during that span.
The first 20,000 fans to Saturday's game receive a Cano bobblehead.
Cano is tied for second in the American League with a .327 batting average and 22 multi-hit games. He has two home runs, 11 doubles and 31 RBIs for the season.
McClendon excited to face former team
SEATTLE -- Manager Lloyd McClendon isn't the mushy type, but he hinted he was looking forward to seeing a lot of familiar faces when the Mariners and Tigers kick-off a three-game weekend set.
McClendon was Detroit's bullpen coach in 2006, then the hitting coach from 2007 to 2013.
"It should be a lot of fun - -if we win," McClendon said. "Ask me at 10:30. I'll let you know then. Obviously I have a lot of friends over there. A lot of people I consider family. It'll be good to see them. Other than that, we'll go about our business and try to win a baseball game."
Will McClendon's knowledge of Detroit's lineup help the Mariners?
"You have ideas, you have ways you think you can exploit and help us be successful, but the fact is once the game starts and the players are between the lines, it's up to the players," he said. "You got to execute. There's only so much I can do or my staff can do."
McClendon said Triple-A Tacoma pitcher Erasmo Ramirez will likely get Maurer's rotation spot. Ramirez (1-4, 6.00 ERA) began the year with the Mariners but was demoted in late April after four consecutive rough outings. He made a spot start against the Athletics on May 7, giving up two runs on six hits and a walk in a 2-0 loss. In five starts with the Rainiers, he is 1-3 with a 4.55 ERA.
