The six-pack is set.

Jon Niese returned to the Mets Wednesday and will take the mound on Sunday in Phoenix against the Diamondbacks rounding out the Mets’ six-man rotation.

Niese who has not appeared with the Mets since landing on the disabled list on June 21 because of a partially torn left rotator cuff threw 80 pitches in a rehab start with Double-A Binghamton on Tuesday and said he expects to throw 95-100 pitches in his big league return.

“Everything felt good” Niese said before the Mets’ 5-0 win Wednesday night at Citi Field. “I feel ready. Each one of my rehab starts I’ve felt pretty strong. Velocity’s been back command for the most part has been where I wanted it. I’m pretty excited about it.”

Manager Terry Collins said Niese still needs to build up more endurance but the Mets manager doesn’t see any reason the left-hander couldn’t come close to throwing 100 pitches on Sunday. Still Collins said the team will monitor the 26-year-old closely.

“As the game goes on and the game goes deeper we’ll make sure if there’s any sign of fatigue any sign of drop in his arm where it looks like his shoulder is getting tired we’ll be on top of that and certainly get him out of there if that starts to happen” Collins said.

Niese said he has no plans to rest his shoulder any more than usual this offseason in order for it to fully heal but the southpaw said he will do additional exercises to strengthen the shoulder which has limited him to 14 games this season. He is 3-6 with a 4.32 ERA.

“It will eventually heal they told me” Niese said. “That’s probably something where the time this offseason will take to heal it. As for now I’m just keeping it strong keeping the inflammation down and so far so good. This rehab it’s not been sore at all and I’ve been able to pitch strong.”
