Managed the Orioles for one year before Davey Johnson took over and gave them some of their best baseball, and what should have been a championship.
Was with the Mets as a minor league pitching coach for 11 years, coaching St. Lucie from 2009–2015, and then become minor-league pitching coordinator from 2016 to 2019. You can imagine the guys he got his grubby finger prints on — deGrom, Harvey, Syndergaard, Matz, Familia, Montero, Fulmer, Lugo, Sewald, etc.
But the rising whale gets the harpoon. He could have labored down there in obscurity, but he had to go and accept the interim pitching coach position, and even though the pitching staff turned around, he was eased into an advisory role at the end of the season.
A coach at heart, and to prove he wasn't a liability, he went to the Dominican Winter League and coached the Toros del Este staff, where his team led the league in pitching (by a lot) and won the DWL championship. He came back and found the Mets advisory role not to his liking, clashed with Bodie Van Wagenen, and sued the Mets for age discrimination when he was fired.
Gave exactly zero fucks. True Story: When he was coaching for the Mets, Fman nicknamed him "Dr. Nefario," and he showed up at Fman's front door and kicked his ass.
