FORT MYERS, Fla. — Tyler Thornburg returned to the mound on Sunday for the first time since thoracic outlet syndrome surgery last summer.

He threw 10 fastballs as a warm up to his first full bullpen session.

The right-hander fired 20 crisp fastballs into the mitt of Christian Vazquez on Wednesday. Vazquez hollered in delight at the end of Thornburg’s session.

Thornburg had the surgery to repair nerves and ligaments in his neck and shoulder in June. He began throwing again in October, gradually building up distance and endurance. Everything led up to Wednesday’s session.

“Pretty darn good,” Thornburg said after the session when asked how it felt. “It’s one of those feelings you realize you miss a lot once you don’t do it for a year I guess.”

Thornburg expects to have two days off from throwing and then throw another bullpen to see how he responds to the session on Wednesday. Thornburg’s process will depend on how he feels after each outing but after three or four bullpen sessions, he could advance to throwing live batting practice.

The 29-year-old said he feels better now than he did in 2016 when he had his best career season, posting a 2.15 ERA and 12.1 strikeouts per nine innings in 67 appearances in Milwaukee.

At that time, he was still navigating intermittent pain before it escalated to the need for surgery.

• Craig Kimbrel revealed at the Red Sox Winter Weekend in January that his infant daughter required surgery for a heart defect shortly after her birth in November.

The first surgery went well, but Kimbrel said his daughter, Lydia Joy, would need a second surgery during spring training.

That surgery will take place this week at Boston Childrens Hospital and Kimbrel has been granted leave from the team to be with his family.

• The Red Sox are asking the city of Boston to change Yawkey Way back to its original name, Jersey Street.

The name has been under fire for years for its connection to what the team’s principal owner has said is the franchise’s complicated racial past under former owner Tom Yawkey.

Yawkey owned the Red Sox from 1933 to 1976 and presided over the last franchise in Major League Baseball to field a black player.

That was in 1959, more than a decade after Jackie Robinson played for the Dodgers.

• Xander Bogaerts hit an RBI double as Boston topped Pittsburgh 4-3 at Fort Myers, Florida.

The Red Sox bullpen threw 62/3 shutout innings.

ASTROS: First baseman Yuli Gurriel had surgery on his left hand and is expected to miss the start of the season.

Astros GM Jeff Luhnow says doctors removed the hook of the hamate bone, which was broken before Gurriel arrived at camp.

Luhnow said he did not know the original cause of the fracture.

Normal recovery time is six weeks, which means Gurriel will miss the first two weeks of the season.

When he returns he will serve a five-game suspension for an inappropriate gesture made toward Los Angeles pitcher Yu Darvish during the World Series.

TWINS: Logan Morrison and the Twins finalized a $6.5 million, one-year contract, a deal that includes a $5.5 million salary this year and an $8 million club option for 2019 with a $1 million buyout.

Morrison agreed to terms last weekend subject to a successful physical and was introduced during a news conference at Twins spring training headquarters in Fort Myers, Florida. The 30-year-old drove in 85 runs for the Tampa Rays last season to go with his career-best 38 homers.

His .868 OPS was higher than that of any Twins player last year.

ROYALS: First baseman Lucas Duda agreed to a $3.5 million, one-year contract with the Royals that allows him to earn $1.3 million more in performance bonuses.

Duda, 32, hit .217 with 30 homers and 64 RBI last year for the New York Mets and Tampa Bay, which acquired him on July 27. He had 58 extra-base hits and a .496 slugging percentage.

YANKEES: With Aaron Judge, Giancarlo Stanton and Gary Sanchez in the lineup together for the first time, Sanchez hit a long home run, Stanton had two hits and Judge hit a hard grounder in Wednesday’s 9-6 spring training loss to the Detroit Tigers.

It was the first loss for New York this spring after opening with five wins.

BREWERS: Catcher Stephen Vogt is expected to miss 2 to 3 weeks because of a strained right shoulder.

The injury occurred last week during a spring training workout. Vogt said he felt something awkward during a drill, but attributed it to getting back into game shape.

Vogt caught Milwaukee’s spring training opener on Friday. He got an MRI after discomfort lingered through the weekend, and the test revealed a strain.
