Johan Santana successfully completed a bullpen session Thursday, and will next pitch a rehabilitation outing for the Brooklyn Cyclones on Sunday.

Santana is on the 15-day disabled list with a sprained ankle and shoulder fatigue, but the team has maintained that its ace is progressing well. If Santana comes through the rehab outing — which will probably be brief, not a full start — without issue, he could start for the Mets on Thursday or Friday.

"He threw good," Collins said. "He feels great."

Because of the uncertainty around Santana, the team has not yet set its rotation for the coming week, including rookie sensation Matt Harvey's Citi Field debut.

"There are all sorts of thoughts going on, because we don't know where we're going to slot Johan in," Collins said.

Harvey is a possibility for next Saturday's game.


Although Omar Minaya is now a senior vice president of baseball operations for the Padres, the former Mets GM will not be at Petco Park for this weekend's series. Minaya told friends that he did not want to be a distraction.
