The Kansas City Royals called up Eric Hosmer (KCA) when Kila Ka'aihua (KCA) failed to hit in the majors this year. Hosmer is off to a good start. While his batting average isn't high at .242, he draws enough walks for a .333 OBP and slugs .515.
So far, pitchers work him outside:
They may not be working him far enough outside, however, as he owns the middle of the strike zone.
Note his ability to hit the low pitch as well. Eric smashes those for line drives with a higher frequency than balls in the middle of the plate. Pitchers have another advantage going outside:
Hosmer has shown good strike zone judgement. He gets the calls at the top and bottom of the strike zone, but so far the outside edge belongs to the pitcher. That's a bit unfair to the rookie. He struck out three times on those outside strikes. With his low number of at bats, it's one reason his batting average is low. I hope the Royals encourage him to keep taking those pitches. Eventually he'll get the calls, and pitchers will be forced into the strike zone where he can smack the ball.
