Bullpen help has been an obvious need for Minnesota and the Twins finally addressed it, acquiring right-hander Kevin Jepsen from the Rays in exchange for minor leaguers Chih-Wei Hu and Alexis Tapia.
Jepsen throws in the mid-90s, but his strikeout rates have generally been underwhelming for a late-inning reliever and his control is poor. This season he has a nice-looking 2.81 ERA, but it comes with a sub par 34/20 K/BB ratio in 42 innings.
For his career, spanning parts of eight seasons for the Angels and Rays, he has a 3.80 ERA with 8.5 strikeouts per nine innings and 3.6 walks per nine innings while holding opponents to a .252 batting average.
Jepsen is a decent enough bullpen arm and should be at least a slight upgrade over the right-handed setup men the Twins have used for most of the year in Blaine Boyer and Casey Fien, but that’s a pretty low bar to clear. He’s making $3 million this season and is under team control for 2016 via arbitration, with a likely cost of at least $5 million.
Hu is a Single-A right-hander with good results and mediocre raw stuff, ranking among the team’s top 20 prospects coming into the season and improving his stock since then. Tapia is a 19-year-old rookie-ball starter signed out of Venezuela and hasn’t really emerged on the prospect radar much yet.
