Aceves, McCutchen, Laffey: SP/RP Qualified Relievers

I have profiled several SP/RP qualified relievers so far this season (here and here and here) with David Hernandez currently being the best out of the bunch. Today I am going to dig a little deeper and look at some SP/RP relievers on the fringe of being owned.

Alfredo Aceves (0.6% owned ESPN) – On the surface, Aceves looks to have pitched OK as a reliever this season with 7 Holds, 2.64 ERA and a 0.99 WHIP. These stats are all smoke and mirrors. The rate stats are being driven by a low BABIP of 0.188. His FIP (4.72) and xFIP (4.60) are much higher.

The one item he has been able to improve has a reliever is his walks. As a starter his walk rate is 5.57 BB/9, but as a reliever it is down to 2.64 BB/9.

I would not count on him padding your rate stats. I could see him being a decent source of counting stats like Holds (Boston should have plenty of leads) or Wins.

Daniel McCutchen (0.1% owned ESPN) – Like Aceves, McCutchen has some nice stats as a reliever, a 3-1 record, 8 Holds, a 1.20 WHIP and a 2.19 ERA. His low ERA is being driven down by a low BABIP (0.265) and HR/FB (6.3%). McCutchen has not been much of a strikeout pitcher in his time in the majors (4.9 K/9) and has walked a few too many batters (3.1 BB/9). All these stats lead to a FIP (3.87), xFIP (4.34) and SIERA (4.13) that are each about twice his ERA.

The only reason I see to own him is if an owner is in desperate need of Holds.

Aaron Laffey (0.0% owned ESPN) – Another player with a nice and pretty ERA (2.39). His ERA is not being suppessed by a super low BABIP (0.280) or HR/FB (13.9%). Instead, he has some how stranded 91.3% of the base runners allowed this season. Sorry for sounding like a broken record, but his FIP (4.61), xFIP (4.00) and SIERA (3.83) are all a bit higher than his ERA. With a K/BB of 1.75, he doesn’t provide much promise.

Also, he is generally not even used as a setup man, so his chances of generating Holds is at a minimum.

Final thoughts

All 3 of these pitchers have an ERA that is not sustainable and provide little in the way of Ks. If you are looking for some SP/RP qualified pitchers, I would look for one mention in one of my previous articles.
