St. Lucie will finish a suspended game with the Charlotte Stone Crabs before its regularly scheduled contest. Either Maine or Perez will pitch in the suspended game, and the other pitcher will start the regular game.
Maine was placed on the disabled list on June 11 with fatigue in his right shoulder. He is eligible to come off the DL on Monday, but the Mets announced earlier in the week that the right-hander would not be ready.
Perez has been on the DL since May 7 with patellar tendinitis in his right knee. He had been rehabbing at Triple-A Buffalo in late May before an MRI exam revealed the knee tendinitis. The left-hander threw 48 pitches in an extended spring contest last Thursday.
There is no timetable yet for Perez's return.
