The Arizona Diamondbacks have released Madison Bumgarner after the pitcher cleared waivers.

The left-hander was designated for assignment on April 20, giving the team seven days to trade him or place him on waivers. Bumgarner wasn't claimed and can sign with any team for a prorated share of the $720,000 major league minimum.

The 33-year-old allowed at least five runs in three of his four starts this season.
