Astros right-hander Cody Bolton went unclaimed on waivers following this week’s DFA and has been assigned outright to Triple-A Sugar Land, the team announced this afternoon. It’s the first outright of his career and he has fewer than three years of MLB service, so he won’t have the option to reject in favor of free agency. Bolton will remain with the organization as non-roster depth in the upper minors.

Bolton, 28 next month, has pitched 20 innings out of the Houston ‘pen this season and been tagged for a dozen runs (5.40 ERA) on 21 hits and 14 walks. Three of those hits have been home runs. He’s fanned 22 of the 95 batters he’s faced (23.2%) despite a paltry 6.6% swinging-strike rate and 22.8% opponents’ chase rate. (League-average in both regards would be 10.8% and 32.5%, respectively.)

Bolton entered the season with only 42 major league frames under his belt. He’s now pitched for four clubs, having previously suited up for the Pirates, Guardians and Mariners as well. Bolton has a deep arsenal, headlined by a fastball that sits 95.1 mph. He also works in a cutter and changeup both averaging about 90 mph, a 94.5 mph sinker, a low-80s slider and, as of this season, an upper-70s curveball.

Although his work in the big leagues has produced an ERA north of 5.00, Bolton has pitched in parts of five Triple-A seasons and worked to a combined 3.32 ERA with a 24.8% strikeout rate and an 11% walk rate. Houston’s bullpen has been among the worst in the sport this season, so Bolton could find himself with another opportunity later this year if he can go on a nice run in Sugar Land.
