Klentak stepped down after a third straight September collapse left the team out of the postseason for the ninth consecutive season. “We’ve made progress but we haven’t made enough progress fast enough,” Phillies managing partner John Middleton said. Klentak was hired in October 2015 by team President Andy MacPhail after serving as assistant general manager for the Los Angeles Angels for four seasons. The Phillies had the worst bullpen ERA in the majors this season and it didn't improve after Klentak acquired four veterans in trades. The Phillies went 161-163 under Kapler before Middleton overruled Klentak and MacPhail and fired him last year.
