Votes of confidence in Mets leadership have come to an end after three years of second-half collapses.
The team fired manager Jerry Manuel on Monday and relieved GM Omar Minaya of his duties, ESPN.com reports.
Jon Heyman, though, reports that Minaya will stay with the team in some capacity.
The Mets $136 million payroll managed a 79-83 record in 2010, and were 204-213 overall for Manuel's tenure.
"We are extremely disappointed in this year's results and the failures of the past four seasons," Mets CEO Jeff Wilpon said. "We need to hire a new general manager with a fresh perspective who will transform this club into a winner that we want and our fans deserve."
Assistant GM John Ricco will act as interim GM.
