MILWAUKEE — The Los Angeles Dodgers placed shortstop Hanley Ramirez on the 15-day disabled list Sunday with a strained right rib cage muscle.

He felt tightness in his right side before Friday night’s game, the start of a three-game series with Milwaukee. He walked in the first inning before being removed in the bottom half.

Ramirez is hitting .277 with 12 homers and 58 RBIs in 100 games for the NL West leaders. He had an MRI on Saturday, and manager Don Mattingly said the severity of the injury was not as bad as initially feared.

The move was made retroactive to Saturday, and Mattingly indicated Ramirez may only need the minimum 15 days to recover.

“We’re probably being a little cautious,” he said. “He could be ready in 10 games but we don’t want to (bring) him back in seven and then have something worse happen and maybe lose him the rest of the year. We want to assure ourselves he’ll be available down the stretch.”

In Ramirez’s absence, Miguel Rojas started at shortstop for the second straight day. The slick-fielding Rojas contributed on offense too. He was 3 for 5, including a double and a run scored in the Dodgers’ 5-1 win over Milwaukee on Sunday.

Ramirez was replaced on the active roster by Darwin Barney, who was called up from triple-A Albuquerque. A Gold Glove Award winner at second base in 2012, Barney will start some games at shortstop, Mattingly said.

Inside pitch

  • Colorado placed outfielder Carlos Gonzalez on the 15-day disabled list with left knee tendinitis and a sprained right ankle. The Rockies recalled first baseman Ben Paulsen from Triple-A Colorado Springs, and he hit a two-run homer off Arizona’s Wade Miley in the first inning Sunday in a 5-3, 10-inning Rockies win.
  • San Francisco recalled first baseman Adam Duvall and put him in the starting lineup for its series finale at Kansas City. Duvall went 0 for 2 with a walk and a strikeout in the Giants’ 7-4 loss. He was among the Pacific Coast League leaders with 26 homers, 84 RBIs and a .596 slugging percentage.
  • Cleveland put outfielder David Murphy and designated hitter-first baseman Nick Swisher on the 15-day disabled list, a day after they both made early exits because of nagging injuries. The Indians recalled outfielder Tyler Holt and infielder-outfielder Zach Walters from Triple-A Columbus.
  • Jacob deGrom, the Mets’ rookie pitcher who has made a run at NL Rookie of the Year, is headed back to New York for tests after lingering soreness in his right shoulder. Top pitching prospects Noah Syndergaard or Rafael Montero could be called up.
  • Washington placed outfielder Steven Souza Jr. on the 15-day DL with a left shoulder bruise and recalled Michael Taylor from Triple-A Syracuse.
  • Angels left-hander Tyler Skaggs will have elbow ligament replacement surgery, likely sidelining him for the 2015 season.
