CHICAGO (AP) — New York Mets ace Johan Santana remains day to day with a strained left pectoral muscle.

Manager Jerry Manuel said the injury is “nothing they think is serious” but is not sure if Santana will miss a start. He’s scheduled to pitch Tuesday against Washington.

Santana left following the fifth inning of Thursday’s 4-2 win over Atlanta. Manuel says Santana will probably throw some long toss on Saturday and possibly a bullpen session.

Santana had little to say before Friday’s game against the Chicago Cubs, telling reporters “I’m good, guys” as he walked into the trainer’s room. He also declined comment after the Mets’ 7-6 loss.

Angel Pagan has been limited lately by tendinitis in his forearm, and shortstop Jose Reyes has been sidelined since Aug. 26 because of a strained right oblique. Manuel says the Mets haven’t discussed shutting him down “at this point.”
