Jake Brentz

After seven years in the minors, toiling for four organizations, Brentz made the Royals roster as a flame-throwing lefty reliever. We went on to collect 15 holds and two saves in his freshman campaign. His 3.66 ERA appears shiny, but his ERA estimators peg it at least half a run shy of expected. Moreso, a 13.3% BB% fueled a high 1.28 WHIP. While an 8.8% BB% over his final 22 appearances is encouraging, Wells' minor league track record indicates he'll be hard-pressed to maintain the reduced level over a full season. On the plus side was a high 27.3% K%. Wells likely won't be the Royals full time closer, but with today's bullpen usage, he could gather a handful of saves with more bountiful holds. Strikeouts are also part of the package, just beware of an incendiary walk rate putting ratios in peril.
