“It's been a blast, but it's time,” the 68-year-old Collins said.
Collins announced he was stepping down after the Mets lost to Philadelphia 11-0, finishing a 70-92 season that began with great expectations but was quickly derailed by injuries.
“It's one of those years you want to forget, and I will. Tomorrow,” he said, saying this season left a “sour taste.”
The Mets were 551-583 overall under Collins, reaching the World Series in 2015 and earning an NL wild-card spot in 2016.
Collins was the oldest manager in the majors and recently said he had no plans to retire after this season. His two-year contract was set to expire after this year. He managed the Mets longer than anyone else.
Collins has managed 13 years in the majors with Houston, the Angels and Mets, going a combined 995-1,017.
“I did it a long time,” he said.
When Collins and Phillies manager Pete Mackanin exchanged lineup cards at home plate, the two men hugged before walking away.
It was announced on Friday that Mackanin would not return as Phillies manager in 2018. Instead, he will transfer to a front office role as senior adviser to general manager Matt Klentak.
A couple fans at Citizens Bank Park held up signs thanking Collins for his efforts.
The New York Post reported last Wednesday that longtime Mets pitching coach Dan Warthen, who predates even Collins on the staff, is likely to be let go. And in the past few days, things turned particularly ugly amid anonymously sourced reports of sniping by players and friction between Collins and the front office — partly over how he's handled the bullpen.
“Terry's a great person. He's helped me out a lot through my baseball career,” catcher Travis d'Arnaud said after the Mets' home finale Wednesday. “He's been a tremendous help for me. He's an amazing person. Fiery person, and definitely molds a lot of players and brings out the fire in a lot of guys.”
Collins ranks second to Davey Johnson (595) among Mets managers in wins.
