ST. LOUIS -- Get ready for a potentially make-or-break series for the New York Mets.
The Mets (62-62) trail the St. Louis Cardinals by 4 1/2 games for the National League's second wild-card spot as the teams open a three-game series on Tuesday at 8:15 p.m. ET at Busch Stadium.
The Mets could have used the team's day off on Monday to skip Niese, but decided to keep the rotation in order because of Steven Matz's shoulder woes and Jacob deGrom's struggles in his last start in San Francisco.
Matz had been lined up to start the series finale, but he instead was placed on the disabled list after his balky shoulder was examined by team doctors on Monday in Manhattan. Matz was diagnosed with a mild shoulder strain and rotator-cuff inflammation. Because of DL backdating, Matz will be eligible to be activated next Tuesday -- the next time his rotation turn comes up. It's not yet clear if he will be ready by then.
Gsellman, who is a combined 4-9 with a 3.99 ERA in 20 starts with Double-A Binghamton and Triple-A Las Vegas this season, is expected to work out of the bullpen. He was scratched from his scheduled Pacific Coast League start on Monday at Tacoma.
Rivera returns to sub for Neil Walker, who is due to be placed on paternity leave and miss the entire series.
The 23-year-old Gsellman, a 13th-round pick in 2011 out of high school in Los Angeles, specializes in keeping the ball on the ground. With Las Vegas, he recorded 2.12 groundouts for every fly out.
TUESDAY'S NEWS REPORTS:
Dwight Gooden refuted Darryl Strawberry's comments that he's a junkie, and told the Post about Strawberry: "He's trying to take the heat off himself. … He's cheating on his wife. He's having an affair with people. … I call him Lucifer. … [Going public] was a weak shot, and he did it to make himself look better, because he is running a drug rehab." Bobby Ojeda tells the Daily News it was wrong for Strawberry to go public with his concerns about Gooden. Read more in Newsday.

@AdamRubinESPN Awesome! I love those moves. Now if they could bench Grandy and get Conforto up here, we're in business.— Jimmy (@ItsjustJimmy) August 22, 2016
