He just has his highest OPS to Left. Since 2007, he's hit 272 balls to left, and 585 to right for better than a 2 to 1 ratio to right. The average for left handed hitters in 2009 was about 1.5 to 1. And as I've already stated, I think most of the reason for his lack of production to right is batting in home stadiums that suppress left handed home runs. For instance, http://katron.org/projects/baseball/hit-location/ allows you to transpose hitters (from last year) between parks. If you take Kotchman's balls in play from Turner and put them in Safeco, he gains 3 home runs easily, and as many as 5. If you add just those 3 homeruns to Kotchman's Atlanta batting line, his OPS goes up 40-50 points (I calculated the Slugging, but nothing else) making him a low .800 OPS hitter, which at least isn't bad for a firstbasemen.
