It might seem like I'm just being a negative A's fan when discussing Fuentes, Rodney, and Shields, finding everything wrong with them because of their uniforms.
But no, I'm just being honest about them. And I'll be honest again here: Kevin Jepsen is a very good reliever.
Ignore the 4.94 ERA. FIP and tERA both have Jepsen at 2.81, and his xFIP and true ERA are 3.53.
A .365 BABIP did Jepsen in in 2009, but that's unlikely to continue, and when it regresses, the Angels will realize that Jepsen is better than Fuentes, Rodney, or Shields.
Jepsen can dial his fastball up to 100 (on rare occasions, he usually tops out at 98), and he backs it up with a vicious cutter-curve combo.
Jepsen is a poor man's Andrew Bailey, and could become a dominant late-game reliever as soon as this season. An ERA over 3.50 would come as a surprise.
