The Boston Red Sox continue to battle injury woes, with third baseman Rafael Devers dealing with a bone bruise in his left knee and outfielder Tyler O'Neill going on the injury list after the two collided during Monday's game.

Devers, a two-time All-Star, underwent an MRI on Thursday. He left Tuesday's game against the Cleveland Guardians with knee discomfort and served as designated hitter during Wednesday's game, going hitless in four at-bats with three strikeouts.

Pittsburgh Pirates pitcher Aroldis Chapman has been suspended two games and fined an undisclosed amount for "inappropriate actions" during Monday's game against the New York Mets, MLB announced Thursday.

The Cleveland Guardians acquired right-hander Pedro Avila from the San Diego Padres for cash on Wednesday.

In a corresponding move, the Guardians transferred infielder Angel Martinez to the 60-day injured list.

The Colorado Rockies placed veteran Kris Bryant on the 10-day injured list Wednesday with a low back strain.

Bryant, 32, is batting just .149 through 13 games this season with one home run, six RBIs and 18 strikeouts. The move is retroactive to Sunday.

San Diego Padres ace Yu Darvish landed on the 15-day injured list Wednesday with neck tightness.

The Padres' Opening Day starter, Darvish last pitched Sunday, allowing three runs on four hits in five innings in a no-decision against the rival Los Angeles Dodgers. The 37-year-old right-hander's designation is retroactive to Monday.

Houston Astros ace Justin Verlander will make his season debut Friday night at the Washington Nationals.

Houston manager Joe Espada made the announcement Wednesday.

"Getting him back is huge because it brings a level of confidence to our team, a boost of confidence that we're going to get someone who's been an MVP, a Cy Young [winner] on the mound," Espada said. "It's [good] for the morale and to get stuff started and moving in the right direction."

Ozzie Albies has been placed by the Atlanta Braves on the 10-day injured list with a fractured big toe on his right foot.

"It's a freak injury, and there's nothing I can do it," Albies said. "Just makes sure I heal fast, and I'm ready to go."

Albies wore a walking boot Tuesday. He said he didn't realize he was injured until he took off his shoe Monday night and was taken for X-rays by a trainer.

"I'm sure once he got inside and the adrenaline stopped flowing and the game juices and all that, you're just seeing him limp around and got pretty sore," Snitker said. "I'm sure that wasn't real comfortable out there."

Jack Leiter, the son of former major league pitcher Al Leiter, is set to make his major league debut for the Texas Rangers against the Detroit Tigers on Thursday.

Texas said Tuesday it intended to select the contract of Leiter, 23, from Triple-A Round Rock, where he is 1-1 with a 3.73 ERA in two starts and one relief appearance this season.

Whitey Herzog, the gruff and ingenious Hall of Fame manager who guided the St. Louis Cardinals to three pennants and a World Series title in the 1980s and perfected an intricate, nail-biting strategy known as "Whiteyball," has died. He was 92.

"Whitey spent his last few days surrounded by his family. We have so appreciated all of the prayers and support from friends who knew he was very ill. Although it is hard for us to say goodbye, his peaceful passing was a blessing for him," his family said in a statement released by the Cardinals.

Astros ace Justin Verlander will throw a side session Tuesday, and if that goes well he'll make his season debut this weekend against the Washington Nationals.

Houston manager Joe Espada made the announcement Monday but wouldn't say which game of the series Verlander would start. The three-game set begins Friday night.

"He's in a good spot," Espada said. "He feels good. He feels confident. He wants to contribute. He knows that we need him on the mound, we need his presence and right now and he's right where he needs to be."
