Matt Garza sucks right?

Some thoughts on Matt Garza from Joe Lemire on SI.com.

There are 108 pitchers who have thrown enough to innings to qualify for the leaderboard on rate stats -- i.e. one inning per team game played -- so it's tough competition to be No. 1 in anything, but Matt Garza is tops in four (admittedly related) categories. He has the highest strikeout rate (14.2 K/9); the highest batting average against on balls in play (.541); the best FIP (0.61), which stands for Fielding Independent Pitching and adjusts ERA for defensive performance; and is tied for the lowest HR rate (with 27 other pitchers). Furthermore, Garza is also tops in hitters swinging outside the strike zone (47.1 percent) and in hitters making contact within the strike zone (96.4 percent).

So when Garza pitches in the zone, he gets hammered, but when he pitches outside the zone he gets guys to swing. Should he only throw balls?
