Mike Young hits too many line drives

I was looking over hardball times' story about Jose Reyes' ground ball tendencies http://www.hardballtimes.com/main/article/should-jose-reyes-hit-more-groundballs /] or lack there of and hit the link at the bottom to League Leaders for fewest infield flies.  A stat with Mike Young as the leader.  So I opened his page and looked at his BIP stats.

Year    LD%     GB%    IF/F    HR/F
2004    24.8%    37.4%    N/A    8.6%   
2005    25.5%    45.3%    10.1%    12.7%
2006    24.9%    48.1%    3.7%    7.9%
2007    27.2%    48.4%    1.5%    6.8%

So his line drives were up, ground balls were similar and infield flies and homers were down.  I'm not sure what really explains this but its almost as if he wasn't trying to hit home runs because he wasn't trying to get under the ball hence his outrageously low IF/F number
