Marcus Giles returns to Atlanta tonight, and he seems to have shaken off his 2006 slump. His OPS of .828 is right on target with his 2004 and 2005 performances. The problem is, Marcus is once again overperforming his PrOPS (predicted OPS) of .744—80 points below his actual OPS.
PrOPS predicts OPS based on the way players hit the ball and does not focus on outcomes. As I have argued before, Marcus is someone who has been lucky throughout his career. Now, maybe Giles is an example of a player that casts doubt on PrOPS’s usefulness; however, I’m confident in it. If I owned him on my fantasy team, I would attempt to dump him now. But hey, that’s just me. Use at your own risk.
