(Reuters) – New York Mets manager Terry Collins has resigned from his post and will take on a front office role with the team the 68-year-old said after their regular-season finale against the Philadelphia Phillies on Sunday.

Collins’ two-year contract had been due to expire at the end of the season.

He finished his seven seasons leading the Mets with a 551-583 record and guided the team to the 2015 World Series – losing to the Kansas City Royals.

“This has been a tremendous run,” Collins said. “I’ve had a great time. Its been a wonderful experience.”

The Mets finished this season second to last in the National League East with a record of 70-92. They lost their final game to the Phillies 11-0.

“I thought that this was a time for change,” said Mets general manager Sandy Alderson.

“Change is difficult. But it comes with baseball. Terry’s a baseball man. He will be till the day he dies.”
