Blue Jays outfielder--third baseman Jose Bautista is an interesting contrast to Rolen: While Rolen is returning to an established level of performance, Bautista, second in the majors with 18 homers through Sunday, is a one-trick pony who is unlikely to fool the AL much longer. In his seventh season Bautista, 29, has become one of the most extreme fly-ball hitters in baseball. More significant than the extra fly balls are their outcomes: After a career in which about one in nine of his flies went for homers, Bautista is going deep on one in five. Home runs per fly ball tends to be a long-term skill for hitters, though, so Bautista's "extra" power is likely due to good fortune. With his high strikeout and fly-ball rates along with the inevitable decrease in his HR-to-FB rate, Bautista is bound to be a power disappointment in the second half.
