Mets pitcher Steven Matz has been scratched from his Monday start in a minor league game because of tenderness in his left elbow.

“There’s a little irritation, and he’s got to work that out,” Mets General Manager Sandy Alderson said on Sunday. “We don’t think it’s anything significant, but it bothers him on extension. He won’t pitch tomorrow, and we’ll see where that takes him over the next four or five days.”

Matz was scheduled to pitch on the back fields at the team’s complex to start the final week of spring training.

Alderson said the problem has bothered Matz for “a period of time”, but that he hasn’t been sent for an MRI.

The GM added that the team doesn’t think the issue is serious, but that it’s “worrisome” because Matz has continued to be injured during his short career with the Mets.

Matz gave up five runs and eight hits in four innings against Miami on Wednesday. He is 1-1 with a 4.26 ERA in four starts this spring.

Matz was 9-8 with a 3.40 ERA in 22 starts in 2016, but was shut down last September and had surgery to remove bone spurs in his left elbow.

The Mets open the season April 3 against Atlanta.

Alex Cobb scratched

Tampa Bay Rays right-hander Alex Cobb has been scratched from a start in a minor league game due to left lower back tightness.

Cobb was scheduled to pitch in an intrasquad game Sunday.

“Probably won’t know anything until (Monday) when Cobb comes in and see how he feels,” Tampa Bay manager Kevin Cash said before the Rays played the New York Yankees. “To my knowledge he could have pitched today.”

Cobb returned from Tommy John surgery late last season and is trying to regain the pre-injury form that had him on track to be the Opening Day starter in 2015.

Shortstop Tim Beckham didn’t play in the Yankees’ game because of hip flexor tightness.

Tigers make moves

The Detroit Tigers released right-handed reliever Mark Lowe, one of several cuts before Sunday’s spring training game against Toronto.

Detroit also optioned catcher John Hicks to Triple-A Toledo, and the Tigers reassigned right-handers Joe Jimenez, Ruben Alaniz, Logan Kensing, Arcenio Leon and Edward Mujica, infielder Dominic Ficociello and outfielders Anthony Gose and Juan Perez to minor league camp.

The Tigers signed Lowe to an $11 million, two-year contract before last season, but he was ineffective in 2016, going 1-3 with a 7.11 ERA in 54 appearances. He had a 5.19 ERA in nine appearances this spring.

In 2015, Lowe went 1-3 with a 1.96 ERA in 57 games with Seattle and Toronto.

Up from Triple-A

The Colorado Rockies selected the contract of first baseman Mark Reynolds from Triple-A Albuquerque.

Reynolds figures to be the starter at first in the absence of Ian Desmond, who is out with a broken left hand.

The 33-year-old Reynolds hit a career-best .282 last season with 14 home runs and 53 RBI. He was limited to 32 at-bats after Aug. 11. He broke a bone in his left hand while swinging a bat, had surgery on Aug. 15, was activated Aug. 31 and broke his left wrist when he was hit by a pitch on Sept. 18.

He re-signed with Colorado in February on a minor-league deal.

Also Sunday, Colorado placed right-hander Chad Bettis on the 60-day disabled list as he deals with testicular cancer. There is no timetable for Bettis’ return.
