Trevor Hildenberger

Hildenberger looked set to be a key piece of the Minnesota bullpen, but struggled to an 8.36 ERA in 14 innings before being demoted in mid-May. He then spent two months on the injured list with a right flexor mass strain. He didn't fare much better when he returned from the injury with a 4.47 ERA at Triple-A and then gave up six runs in 2.1 innings in three big league appearances in September. Hildenberger doesn't have an overpowering fastball, but the sidewinder is still able to miss bats at a decent clip (8.3 K/9) thanks to a deceptive delivery and solid movement on his secondary pitches. However, Hilldenberger's velocity declined to just an 87.8 mph average fastball last season, which made it hard for him to set up his off-speed offerings. It's hard to read too much into his season given his injury, but he likely faces an uphill battle to win a major league bullpen job until he can prove himself again in the minors.
