PHOENIX -- The D-backs officially released left-hander Madison Bumgarner on Wednesday. The veteran starting pitcher was designated for assignment last week and went through waivers unclaimed.

Bumgarner was signed to a five-year, $85 million free agent deal prior to the 2020 season, and he finished his tenure in Arizona with a 15-32 mark and a 5.23 ERA in 69 starts.

The D-backs will be responsible for paying the nearly $34 million left on Bumgarner¡¯s contract. If he were to hook up with another team, that team would be responsible only for paying him the Major League minimum.

¡°Just not very good,¡± Bumgarner said after his final start for the D-backs on April 19. ¡°Haven't been very good. It's frustrating. I obviously am trying to do better, putting in the work. It just hasn't shown up yet.¡±

Bumgarner, 33, spent his first 11 MLB seasons with the Giants and was an All-Star four times. Owner of a 134-124 career record with a 3.47 ERA, he¡¯s noted for his postseason success. Bumgarner, a member of three Giants World Series championship teams, is 4-0 with a 0.25 ERA in five World Series games. He was named MVP of the 2014 World Series and NLCS.
