The Baltimore Orioles placed first baseman Chris Davis on the 15-day disabled list Sunday with a strained left oblique muscle.

The move is retroactive to Saturday. Davis was injured during Friday night's game against the Kansas City Royals.

Davis expressed confidence before Saturday's game that he could avoid a trip to the DL, but the club decided to put him on it a day after the results of an MRI were revealed.

Nick Markakis, usually an outfielder, started at first base in place of Davis on Sunday. He also filled in for Davis on Saturday.

Davis is batting .250 with two home runs and 13 RBIs this season. He led the major leagues with 53 homers and 138 RBIs last year.

---The Washington Nationals placed outfielder Bryce Harper on the 15-day disabled list with a bruised thumb. The move is retroactive to Saturday.

Harper was injured during Friday night's game against the San Diego Padres while sliding into third base. He did not play Saturday. Harper is batting .289 but has just one home run in 83 at-bats.

---Milwaukee Brewers pitcher Matt Garza told Chicago Cubs right-hander Jeff Samardzija to "pitch your way out of there," if he wants to play for a winning team.

Samardzija has a 1.53 ERA in his first five starts this season but is without a win. He has been the subject of trade speculation as the Cubs are building up their minor league system. He is eligible for free agency after the 2015 season.
