After battling elbow soreness throughout camp, Stephenson opened last season on the injured list. He was activated in mid-April and struggled to a 5.14 ERA and 1.43 WHIP over 14 innings with Pittsburgh. An early-season trade to Tampa Bay accompanied a pitch mix change for the right-hander, as Stephenson implemented a cutter that was devastating to opposing hitters. In fact, it was one of the best pitches in all of baseball, generating a 59.9% whiff rate that was second-highest in the league among all pitch types. It helped the 30-year-old generate a career-best 38.8% strikeout rate, 24.0% swinging strike percentage and 30.4 K-BB% that was second-best among qualified relievers. Stephenson's breakout season and career-best ratios -- including a 0.88 WHIP -- should land him in the closer role with the Angels after he signed a three-year deal in January. Read Past Outlooks
