After a historically ineffective season for what was expected to be a good pitching staff, pitching coach Dan Warthen was reassigned in the Mets’ organization and ultimately chose to leave to join the Texas Rangers. The team decided it was time for a new approach after such a disappointing and injury-ridden season for the starting pitchers. Mets starters prevented runs at least effective rate in team history in 2017, posting a 5.14 ERA and league-adjusted 124 ERA-, both of which are the worst in Mets history. Mets starters allowed baserunners at the second-worst rate in Mets history last year with a 1.
Dan Warthen’s Mets tenure ended poorly, but his prior contributions to the team shouldn’t be forgotten.
