Not all power outages are equal

On Thursday's Fantasy Baseball Today, we unveiled our sabermetric leaderboards (VIDEO), focusing this time on Isolated Power (Iso) and xFIP. Four of the hitters on the Iso trailers list are pretty surprising: Billy Butler, Robinson Cano, Wil Myers and Carlos Santana.

Iso is the per-at bat rate at which a hitter gets extra bases, and all four hitters had Isos below .050 heading into Thursday's games. That means for every 20 at-bats, none of them was averaging even one full extra base.

Butler is the only qualifying batter to have a .000 Iso, meaning he has no extra-base hits. As I discussed during the segment, 29 of the 39 balls (or 74 percent) that Butler has hit have been grounders, and that is an astoundingly high rate. Cano's grounder rate -- at 58 percent -- is also discouraging but not nearly as alarming.

Not all power slumps are the result of extreme ground ball rates, though. Myers has struck out 16 times in 50 at-bats, and it's difficult to produce much of anything when you're making that little contact. Santana has yet to hit a homer, but he would likely have more doubles if not for a .205 BABIP that looks fluky-low.

Even with such a small sample, Butler's grounder rate is so extreme that he merits benching next week. As unproductive as Cano, Myers and Santana have been, none is so far off course as to be benchable for the foreseeable future.
