I think Utley, Rollins, McLouth, Adam Lind and Carlos Pena entered a blood-pact to hose my fantasy team.
Seriously though on the year Utley's BB% is up (16.7% vs 11.2% career, K% is down (15.3% vs 18.1% career) and adj HR/AB is in-line with his career (5.8% vs 5.9%). Its his .272 BABIP this year that is low compared to his .318 career BABIP.
However, remember he had a pretty good April but has stunk in since about the start of May. If you just look at numbers since then his adj HR/AB has been 3.7%, almost 50% lower than his career and his BABIP is .269. So he could be playing through an injury (with Rollins out maybe he doesn't want to leave the entire middle infield to backups), or he could be getting unlucky and started pressing.
I'd like to see those charts people do on where and what he's swinging at to see if he is possibly chasing pitches out of the strike zone more (a sign he's pressing) or if he's making contact with more bad pitches that are harder to hit into the stands and are more likely to become outs.
While there is still the possibility of an injury the fact that he had a good April makes me feel a little better than if he'd started off terribly and not improved for 2.5 months (McLouth). I still think of Chase as a buy-low and probably will until the 2nd to last day of the year
