Mets' Carrasco suffers low-grade oblique strain, could miss 3-4 weeks

The New York Mets lost a key member of their rotation for the stretch run, as right-hander Carlos Carrasco was diagnosed with a left oblique strain, the team announced Tuesday.

While an MRI revealed the injury is a low-grade strain, Carrasco could be sidelined for three-to-four weeks.

Carrasco lasted just two innings against the Atlanta Braves on Monday before departing with what the team initially called left side tightness.

The 35-year-old had been enjoying his first healthy season in some time, emerging as an important piece of New York's rotation while the team was without both Max Scherzer and Jacob deGrom. In 23 starts this season, Carrasco owns a 3.92 ERA, 3.65 FIP, and 1.30 WHIP with 124 strikeouts and 33 walks.

In his absence, the Mets could stretch out Tylor Megill and add him to the rotation once he returns from the injured list. Left-hander David Peterson, who's currently at Triple-A Syracuse, is another option.

A corresponding roster move has yet to be announced. However, right-hander Stephen Nogosek has a locker with the team in Atlanta, meaning he's likely to be called up from Triple-A, according to Anthony DiComo of MLB.com. The team is also recalling reliever R.J. Alvarez from Syracuse and optioning Adonis Medina, DiComo reports.

The Mets are also calling up one of their top prospects in third baseman Brett Baty, sources told ESPN's Jeff Passan. Baty is expected to be active for Wednesday's game, per DiComo.

Baty, ranked as the Mets' No. 2 prospect and No. 18 overall by MLB.com, has rocketed through the team's farm system this season. The 22-year-old is hitting .315/.410/.533 with 19 homers and 60 RBIs across 95 games split between Double-A Binghamton and Syracuse. He played only six games in Triple-A, all over the past week.
