First part is incorrect. Here is a little guessing game. Guess which one is McGehee's out of zone swing percentage. Is it A.) 29.2% B.) 40.6% C.) 34.7% D.) 31.6% He maybe out of balance and his bat speed may have slowed down which would explain for the poor hitting by McGehee. It is correct, though. His O-swing% is 29.2%, but his Z-swing% is only 60.8% (career low). Only 46% of his pitches seen are in the zone (also a career low), so he is seeing more non-strikes and swinging at them at the same % as he has in his career -- hence, he's swung at way more balls this year than in previous seasons. Casey has completely lost the ability to hit for power, his ISO is lower than every player with 200 PA's on the team, except for Kotsay.
