Jon Niese will get his first start since July 10 and since returning to the Mets when the Mets face the Diamondbacks in Wednesday's series finale in Arizona.
After Logan Verrett was sent to Triple-A Las Vegas Saturday, Niese has a chance to earn the No. 5 spot in the rotation.
Niese had a 5.13 ERA in 18 starts with the Pirates before being demoted to the bullpen after the All-Star break. The Mets re-acquired him Aug. 1 for Antonio Bastardo.
Niese said being back with pitching coach Dan Wathen has made a difference.
