The Mets are now without exactly one half of their regular starting lineup.
A day after Jeff McNeil expressed optimism he would be able to return to the lineup Thursday after sitting on Wednesday due to hamstring tightness, McNeil -- who has not yet had an MRI -- has been placed on the 10-day IL.
McNeil said Thursday that he feels the injury is minor and that he hopes to be back as soon as the minimum 10 days are up.
Joining McNeil on the 10-day IL is Robinson Cano, who exited Wednesday night's game due to quad tightness after running out a ground out.
To replace McNeil and Cano on the roster, the Mets called up infielder Luis Guillorme and RH reliever Ryan O'Rourke from Triple-A Syracuse.
Along with McNeil and Cano, the Mets are also without Brandon Nimmo (neck) and Michael Conforto (concussion).
Conforto could be close to a return, though, with him expected to further ramp up baseball activity Thursday before being reevaluated.
