Former Mets manager Terry Collins announced on Thursday (via Jon Heyman of MLB Network) that he has retired.

Collins has spent the last couple of years as a special assistant to the general manager for the Mets. You could see him in the back fields during minor league spring camp still watching and offering advice.

The 71-year-old was of course at the helm for the Mets the last time they made the playoffs in 2016 and for their World Series run back in 2015.

Collins most memorable moment as a manager with the Mets came after Noah Syndergaard threw behind Chase Utley. Syndergaard was ejected, and Collins was irate. The exchange between Collins and umpire Tom Hallion is an all-time classic.

In 1971, Collins was drafted by the Pirates and played parts of 10 seasons in the minor leagues. He moved to managing in 1981 with the minor league Lodi Dodgers.

Collins would take over as the Astros managers in 1994, he spent three seasons there before moving to the Angels as their manager for parts of three seasons.

After a stint of managing in Japan, Collins was hired by the Mets in November of 2010. He went 551-583 as the Mets manager from 2011 through 2017. He’s the Mets all-time leader in games managed (1134) and second in wins (551).
