Red Sox knuckleballer Steven Wright underwent what the team called successful knee surgery on Monday in New York.
Wright, 32, is expected to be ready for spring training in 2018 after having the cartilage restoration procedure on his left knee performed by Dr. Riley Williams III at the Hospital for Special Surgery.
Wright, who went 1-3 with an 8.25 ERA in five starts, went on the disabled list last month with the injury and opted last week to have the surgery.
An All-Star last season when he went 13-6 with a 3.33 ERA, Wright's season ended in August after he injured his right shoulder while pinch-running in a game against the Dodgers.
The Red Sox traded infielder Deven Marrero to the Arizona Diamondbacks for a player to be named or cash.
Sox president of baseball operations Dave Dombrowski made the announcement on Saturday.
Marrero, 27, was fighting for one of the final roster spots as a bench player, along with utility man Brock Holt. The first-round pick in 2012 out of Arizona State had spent his entire pro career with the Red Sox organization. He appeared in 109 major league games from 2015-17, making 50 starts at third base, nine at second base, and five at shortstop.
In 2017, the right-handed hitter played in a career-high 71 major league games, batting .211 with four home runs and 27 RBI.
Red Sox ace Chris Sale is expected to be able to make his Opening Day start after he was struck in the left leg by a line drive off the bat of the Houston Astros' J.D. Davis in the first inning on Saturday in Fort Myers, Fla., and had to leave his final spring training start.
After being examined by team medical personnel on the field, Sale walked back to the dugout. He was taken for precautionary X-rays which showed no structural damage.
The Red Sox said Sale sustained a contusion on his left leg. "I don't see anything lingering from this. It looked a lot worse than it was," Sale told reporters. "It scared the hell out of me,”
Sale is scheduled to be the Red Sox Thursday in the season opener against the Tampa Bay Rays in St. Petersburg, Fla. Manager Alex Cora and Sale said he'd be OK to make the start.
