John Maine threw a simulated game at Citi Field today, saying it went well and that he felt OK.

Maine is slated to pitch Sunday’s first game of the Mets-Phillies doubleheader, which will mark his return from the DL after a three-month absence.

Maine made one rehab start in the minors, pitching four innings for St. Lucie in high Single-A last Saturday. He estimated he would throw 60 pitches Sunday.
