LF Yoenis Cespedes (hamstring) and C Travis d'Arnaud (wrist) are back in the Mets' lineup on Tuesday night.
However, Cespedes may be scratched from the lineup if the game is played in inclement weather, Terry Collins said.
Cespedes has not played since exiting last Thursday's game with the hamstring issue. He was on deck to pinch hit Sunday night when the Mets made the final out of the game against the Nationals.
D'Arnaud hasn't caught since April 19, but pinch-hit in all four-games since, going 0-for-4.
Meanwhile, Triple-A infielder Matt Reynolds is on his way to New York to possibly join the Mets, Las Vegas reporter Betsy Helfand tweeted late Monday night.
According to Helfand, Reynolds has spent most of his time playing left field this season.
In 96 plate appearances for the Mets in 2016, Reynolds hit .226 with a .266 OBP and 11 extra base hits in 47 games, during which he played second and third base, shortstop and left field.
The Mets have been carrying 13 pitchers, meaning the bench has been made up of just four players.
1B Lucas Duda (elbow) and infielder Wilmer Flores (joint infection) are both eligible to return from the 10-day disabled list April 30.
IF Asdrubal Cabrera, who is in Tuesday's lineup, didn't play Friday, but played on Saturday and Sunday despite dealing with multiple aches and pains -- including a tight hamstring. He was in visible pain Sunday night after attempting to leg out a single, though he remained in the game.
