NEW YORK — New York Mets outfielder Michael Conforto dislocated his left shoulder Thursday, collapsing and writhing in pain after swinging at a pitch.

The All-Star slugger was hurt in the fifth inning against the Arizona Diamondbacks, yet another blow to a team beset by injuries all season and now out of contention.

With two out and runners on first and second, Conforto swung through a 95 mph fastball by Robbie Ray. Conforto instantly collapsed and grabbed his shoulder. He stayed down for about 40 seconds before being helped to his feet by Manager Terry Collins, trainer Ray Ramirez and a member of the coaching staff.

Conforto is batting .279 with 27 home runs and 68 RBI.

ORIOLES: An MRI performed on closer Zach Britton’s left knee revealed no structural damage, according to a source.

Britton has been pitching through the knee injury since 2014 but said he did feel extra soreness in the joint while warming up Wednesday, when his AL-record streak of 60 straight saves ended.

Though the results of the MRI were positive, it appears the club has not yet determined whether the problem will land Britton on the disabled list.

TWINS: Minnesota put catcher Jason Castro on the seven-day disabled list with a concussion and recalled outfielder Zack Granite.

Castro took three foul balls off his face mask in Wednesday night’s 4-3 loss to the White Sox.
