Finger will keep Thor on the shelf

ATLANTA — Noah Syndergaard’s sore right index finger isn’t worse than originally anticipated, but for now he is taking a break.

The Mets right-hander received a second opinion on the strained ligament in his finger earlier this week and won’t resume throwing until the soreness subsides.

“It’s tender to the touch,” manager Mickey Callaway said before the Mets’ 2-0 loss to the Braves on Wednesday.

Syndergaard will begin a throwing progression when ready, and Callaway said the pitcher will likely need a minor league rehab start before rejoining the Mets rotation.

Syndergaard last pitched for the Mets on May 25 in Milwaukee. The finger subsequently flared up, forcing Syndergaard to miss his next three starts, including Sunday against the Yankees in the Subway Series finale.

Seth Lugo, who entered the rotation in Syndergaard’s place, will remain a starter and pitch Friday in Arizona. Lefty Jason Vargas, who hasn’t pitched in over a week, is scheduled to face the Diamondbacks on Thursday. Steven Matz was scheduled to start Thursday, but was pushed back to Saturday because of a blister on his middle finger.

The Mets claimed righthanded reliever Chris Beck off waivers from the White Sox. He is scheduled to join the team on Thursday in Arizona.

Callaway recommended Beck to team brass as he saw plenty of him as the Indians’ pitching coach in recent seasons.

“I have seen this Chris Beck kid pitch quite a lot and he’s got some electric stuff,” Callaway said.

Callaway’s first career managerial ejection on Tuesday had collateral damage: The manager said his daughters, ages 12 and 9, were watching on TV and started crying when they saw their dad arguing with the umpire.

“They couldn’t understand why daddy was yelling at somebody,” Callaway said.
