Noah Syndergaard has joined the New York Mets’ long list of ailing players.

The right-hander was placed on the 10-day disabled list Tuesday with a sore right index finger, though the Mets are hopeful he will only miss one start.

An MRI and examination confirmed a strained ligament. If all goes according to plan, Syndergaard would throw a bullpen session this weekend and return to the rotation next week.

Syndergaard was scheduled to pitch Wednesday in the series finale against the Braves. Jason Vargas will move up to make the start after three days of rest.

Vargas is 1-3 with a 10.62 ERA in five starts this season.

Syndergaard is 4-1 with a 3.06 ERA and 76 strikeouts in 64⅔ innings as one of the Mets’ aces, along with Jacob deGrom.

Right-hander Gerson Bautista, who was called up from Triple-A Las Vegas to serve as an extra player for the doubleheader, will now remain with the team.

McCann on DL

Astros catcher Brian McCann, in a 1-for-26 slide that has dropped his batting average to .219, was put on the 10-day disabled list on Tuesday because of right knee soreness and returned to Houston.

Tim Federowicz’s contract was selected from Triple-A Fresno before Tuesday night’s game at the New York Yankees. Max Stassi was in the starting lineup and will see most of the time behind the plate while McCann is sidelined. The 34-year-old McCann was a seven-time All-Star while with Atlanta from 2005-13.

Federowicz, 30, is a six-year big league veteran who spent last year with San Francisco.

Angels’ pitchers out

The Los Angeles Angels’ righty Blake Wood is scheduled to have season-ending surgery to repair ligament damage in his elbow on Wednesday. Right-hander Matt Shoemaker had surgery on his forearm on Tuesday.

Wood also had elbow surgery in 2012. He was 1-0 with a 2.31 ERA in 13 appearances this year.

Shoemaker made his only appearance of the season March 31 at Oakland, starting and lasting 5⅔ innings to beat the Athletics. He was moved to the 60-day disabled list on May 19.

Ohtani to return

Shohei Ohtani will return to the mound for the Angels in a game at Detroit. The two-way Japanese sensation had his usual turn Sunday skipped as Los Angeles tries to manage his workload. Ohtani (4-1, 3.35) threw 110 pitches against Tampa Bay in his previous start — his most in America so far — and has a 2.25 ERA in three May starts.

Reyes back off DL

Alex Reyes is set to return to Cardinals for the first time since his brief rookie season in 2016. The hyped right-handed prospect missed all of last season following Tommy John surgery and he’ll come off the DL to make his season debut against NL Central-leading Milwaukee.

Reyes struck out 44 in 23 innings during his minor league rehab assignment, including nine straight batters during his final start with Triple-A Memphis.
