CLEVELAND — Indians All-Star reliever Andrew Miller has been placed on the disabled list for the second time in 20 days with knee tendinitis.

Also Tuesday, Cleveland placed starter Danny Salazar on the 10-day DL with elbow inflammation.

Miller made just seven pitches – all fastballs – in Monday night’s win over Boston before taking himself out. The left-hander was making his second appearance since being activated from the DL on Friday.

The Indians are hoping that rest will help Miller, who was a key in them getting to the World Series last year. While he’s had another solid season, Miller has not been nearly as dominant and his velocity has dropped considerably in the past month. He’s 4-3 with a 1.65 ERA in 38 games.

DIAMONDBACKS: Jeff Mathis has been placed on the 10-day disabled list with a broken right hand, leaving the Arizona Diamondbacks without their top catcher as they make a playoff push.

Manager Torey Lovullo says it’s too early to tell whether Mathis will miss the rest of the season. The 13-year major league veteran, valued for his fine defense and leadership, was injured Monday night against the New York Mets when his bare hand was hit by a foul ball.

In other moves Tuesday, the Diamondbacks reinstated outfielder Reymond Fuentes from the 10-day DL and recalled right-hander Jake Barrett from Triple-A Reno to provide a fresh arm in the bullpen. Right-hander Jimmie Sherfy was optioned to Reno after pitching a perfect ninth inning Monday for his first major league win.

ROYALS: All-Star catcher Salvador Perez came off the 10-day DL.

Perez was sidelined by a strain on the right side of his chest. Perez, the MVP of the 2015 World Series, is hitting .278 with 21 homers and 65 RBI in 99 games.

DODGERS: Starting pitcher Alex Wood and rookie star Cody Bellinger went on the 10-day DL.
