FRAZIER, A TRUE MET, BACK ON DL

Welcome to life with the Mets, Todd Frazier.

The 32-year-old third baseman, who had never gone on the disabled list in his first seven years in the majors, was placed on the 10-day DL for the second time this season on Monday, this time with a left rib muscle/intercostal strain.

Frazier, who is hitting .219 with 10 home runs and 32 RBI this season, said he felt the discomfort while swinging during his at-bats on Sunday.

“I felt it in my first at-bat,” he said. “I didn’t really think anything of it. Second at-bat I reached out for a changeup I felt it a little more and third at-bat was just really uncomfortable…. I talked to them after the second at-bat and said I’m feeling a little something but I think I’ll be all right. It wasn’t.”

Frazier underwent an MRI, which revealed no structural damage, and received a cortisone shot to help expedite the recovery process.

“Doctor said the injection usually helps guys out right away,” he said. “Whatever that means, right away, whether a day or two, I’m on the 10-day DL.”

Spending time on the disabled list is new for Frazier, who had his first DL stint of his career back in May when he missed four weeks with a strained left hamstring.

THOR CLOSE TO RETURN

Mickey Callaway praised Noah Syndergaard’s rehab outing with the Brooklyn Cyclones on Sunday and said he was “optimistic” the righthander’s next start would be for the Mets.

The right-hander threw 71 pitches, 46 for strikes, over five innings and allowed one run on two hits and a walk while striking out seven. He used his full repertoire and topped out a 99 miles per hour. “He looked really good,” Callaway said. Syndergaard has been on the disabled list since May 26 with a strained right index finger. He was scratched from a scheduled return against the Yankees in early June when his finger swelled up after playing catch. Callaway brushed aside concerns over Syndergaard’s injury history before Monday’s double-header against the Phillies. “When you’re talking about lats or a finger, those are just things you really can’t control,” Callaway said.

VARGAS REHABS

Jason Vargas (calf ) tossed six shutout innings, allowing just one hit and no walks while striking out nine in a rehab start for the Brooklyn Cyclones on Monday.

“It felt good to get out there on the mound in a competitive situation again,” he said. “I was happy with how I threw. I was able to work on all of my pitches and, physically, I came out feeling great.”

Callaway said before Monday’s doubleheader he hoped Vargas, who has been on the disabled list since June 20, could return to the team for his next start.
