The Baltimore Orioles placed center fielder Cedric Mullins on the 10-day injured list Tuesday and replaced him on the roster with former New York Yankees outfielder Aaron Hicks.

The Orioles announced the signing of Hicks and activated him for Tuesday night's home game against the Cleveland Guardians.

Houston Astros right-hander Lance McCullers Jr. is no longer throwing off the mound and is back to throwing on flat ground in his bid to return from a muscle strain in his forearm.

McCullers, who first experienced soreness in the forearm in February, had been throwing bullpen sessions earlier this month. He has yet to pitch in a game this season.

"We have to take it slow with Lance until we know that he's 100 percent. That's where it is right now," Astros manager Dusty Baker told reporters Monday.

The Tampa Bay Rays placed closer Pete Fairbanks on the 15-day injured list Monday because of left hip inflammation.

Fairbanks said his hip "locked up" on him while warming up before the ninth inning of Sunday's 11-10 win over the Los Angeles Dodgers. He did not enter the game.

The San Francisco Giants placed infielder Thairo Estrada on the 10-day injured list Saturday with a sprained left wrist.

Infielder David Villar was recalled from Triple-A Sacramento in a corresponding transaction.

Milwaukee Brewers shortstop Willy Adames was placed on the seven-day concussion list Saturday after he was hit by a line-drive foul ball while in the dugout Friday night.

He spent the night in a Milwaukee hospital as a precaution.

Teammate Brian Anderson was batting in the bottom of the second inning against the San Francisco Giants when he hit a line drive that struck Adames, with video showing the ball appearing to hit him in the head or face.

Brewers shortstop Willy Adames was to spend the night in the hospital after being struck by a foul ball from teammate Brian Anderson while watching from the dugout during Friday night's game against the San Francisco Giants.

"He was alert and responsive as he left, and then we got pretty good news at the hospital, too," Milwaukee manager Craig Counsell said after the Giants' 15-1 win. "Obviously, he's in pain. But I think overall I think not bad news, considering how scary it was."

Counsell said that tests revealed no fractures, but Adames would remain in the hospital overnight "just for monitoring purposes" and would get placed on the injured list.

Carlos Correa has a foot injury that could land him on the injured list, according to Rocco Baldelli.

An MRI exam confirmed a muscle strain in the arch of Correa's left foot in addition to plantar fasciitis in his heel.

Correa, 28, wasn't in the lineup for the Minnesota Twins on Wednesday.

"I think we get to Friday and some of our decisions might be made for us," Baldelli said.

The Houston Astros believe Lance McCullers, Jr. can return "probably somewhere closer to the All-Star break, or after," according to general manager Dana Brown.

There's still some fluidity "depending on whether we can get him built up to start," Brown added.

McCullers hasn't pitched yet this season after suffering a forearm strain early in Spring Training.

He logged just 47 2/3 innings last season, posting a 2.27 ERA and 50 strikeouts against 22 walks.

Jose Quintana has been cleared to begin throwing after tests on his rib came back clean.

Quintana had bone-graft surgery in March to repair a rib fracture, during which a benign lesion was found.

"It's time to get ready for baseball," the New York Mets left-hander said.

Quintana, 34, signed a two-year contract worth $34 million this past offseason.

The Los Angeles Dodgers placed left-hander Julio Urias on the 15-day injured list retroactive to Thursday with a strained left hamstring and recalled RHP Wander Suero from Triple-A Oklahoma City.

Los Angeles made the move Saturday just a few hours after manager Dave Roberts said he expected Urias to make his next scheduled start Tuesday at Atlanta.
