Boston Red Sox right-hander Tanner Houck’s attempt to come back this season is over.

Manager Alex Cora said Saturday that Houck will undergo Tommy John surgery.

An All-Star last season, the 29-year-old Houck went on the injured list in mid-May with a right flexor strain after going 0-3 with an 8.04 ERA in nine starts.

“Tanner’s going to have Tommy John surgery,” Cora said before the Red Sox faced the Houston Astros at Fenway Park.

“He went to see Dr. Meister there in Texas and that was the recommendation,” Cora said. “We don’t have a date yet, but he’s going to have it.”

Houck had a strong 2024 season, finishing seventh in the American League with a 3.12 ERA in 30 starts, but was only able to make five rehab appearances after going on the IL.

“Tough year for him, tough year for us,” Cora said of the season-ending news. “But he’ll kill the rehab, he’ll do his job, and when he comes back, he’s going to be OK.”

Houck earned his first All-Star appearance by going 8-6 with a 2.54 ERA in the first half. He struggled after the break, going 1-4 with a 4.23 ERA.

He worked an inning at the All-Star Game in Texas last year, giving up three hits including a homer to Shohei Ohtani.

He’s the third Boston starting pitcher to suffer a season-ending injury. Hunter Dobbins tore the anterior cruciate ligament in his right knee covering first base last month and Kutter Crawford underwent right wrist surgery.

ROCKIES CLOSER HALVORSEN suffers ELBOW injury: ‘It don’t look good’

The Colorado Rockies’ win over Pittsburgh on Saturday was dampened with an elbow injury to closer Seth Halvorsen.

The hard-throwing right-hander left after tossing five pitches in the ninth inning, and the initial outlook isn’t encouraging.

“It don’t look good,” interim manager Warren Schaeffer said. “I’ll let you know (today).”

Halvorsen, who leads the Rockies with 11 saves, was facing Pirates pinch hitter Spencer Horwitz to open the ninth and Colorado leading 8-4. He was ahead 0-2 in the count and then threw three straight balls, the last one at 99 mph.

Immediately after that pitch he bent over and dangled his right arm, prompting Rockies head trainer Keith Duggar to jog to the mound to check on him. After a brief discussion Halvorsen left the game, with Dugan Darnell coming on to finish the 8-5 win.

back spasms shelve RANGERS’ CARTER

Texas Rangers outfielder Evan Carter was placed on the 10-day injured list Saturday because of back spasms and outfielder Alejandro Osuna was recalled from Triple-A Round Rock to replace him on the active roster. Carter, 22, is hitting .238 with four home runs and 21 RBIs this season.
