Frazier sidelined by oblique injury

PORT ST. LUCIE, FLA. >> The Mets are missing a pair of injured infielders, and the calendar hasn’t even reached March.

Third baseman Todd Frazier injured his left oblique muscle and will return to New York for a cortisone injection, the second Mets infielder to get hurt at spring training after fellow infielder Jed Lowrie.

The 33-year-old Frazier had an MRI that revealed the injury.

“I was hitting the ball great, and then I felt a little tightness in my left side,” Frazier said Tuesday.

Frazier said he had not experienced the injury before.

“I thought I was doing everything right,” he said. “I’m frustrated, very frustrated myself. It’s just one of those things where you come into the year all healthy and ready to roll and this happens. It’s not fun.”

Frazier hit 18 homers and drove in 59 runs in 115 games last year, when he went on the disabled list for the first two times in his career.

He altered his approach to spring training this year.

“I wanted to try something different — going slow. And this has to happen,” Frazier said. “It’s not the best start. Luckily it happened in spring training and we can nip this thing in the bud and get ready for the season.”

New general manager Brodie Van Wagenen isn’t sure of the seriousness of Frazier’s injury.

“It’s hard to tell. I think with obliques it’s sort of a day-to-day progression to see how it evolves. The MRI wasn’t overly alarming, but clearly we’re going to shut him down and start building him up from there,” Van Wagenen said.
