BALTIMORE — The Baltimore Orioles placed struggling right-hander Chris Tillman on the 10-day disabled list with a lower back strain.

The move came less than 24 hours after Tillman yielded six runs in 11/3 innings against the Royals on Thursday night, leaving him at 1-5 with a 10.46 ERA.

After the game, he said: “I’m just not getting it done. It’s not good right now. I’ve got to make better pitches.”

Tillman will be replaced on the roster by right-handed reliever Jimmy Yacabonis, who was recalled from Triple-A Norfolk.

ASTROS: Outfielder George Springer is day to day with a bruised left elbow after being hit by a 92 mph pitch from Rangers starter Cole Hamels in the fourth inning Friday night.

Springer remained on the ground for nearly two minutes as Houston’s medical staff attended to him. He finished the inning as a baserunner, but was replaced in center field in the top of the fourth by Jake Marisnick.

METS: The team will be without outfielder Jay Bruce for its weekend series in Philadelphia.

Bruce was placed on the paternity leave list Friday with his wife due to give birth to the couple’s second child. He was replaced on the 25-man roster by first baseman Dominic Smith, who was recalled from Triple-A Las Vegas.

The Mets also placed right-hander Hansel Robles on the 10-day disabled list, retroactive to Wednesday, with a sprained right knee.

Left-hander Buddy Baumann was recalled from Triple-A, but he’ll have to sit out Friday night’s game against the Phillies to serve a one-game suspension for his role in a brawl with Colorado on April 11. Baumann was pitching for San Diego then.

• The Mets will skip struggling left-hander Jason Vargas’ next turn in the rotation on Tuesday. Manager Mickey Callaway said that Vargas will instead throw a simulated game before the Mets host Toronto. Vargas is 0-3 with a 13.86 ERA since returning from surgery on his right hand.

NATIONALS: Outfielder Adam Eaton was transferred to the 60-day disabled list, a day after he had surgery on his left ankle.

The 29-year-old Eaton has been on the disabled list since April 11, and will be out until at least early June. The move Friday was made retroactive to April 9, and the Nationals haven’t announced a timetable for his return.
