Here's something that is not clear to me: would Tracy consider using McLouth every day in centerfield? Or is he strictly regarded as a corner outfielder? I know his defense is not as good as Duffy's, but when you play a guy in centerfield, fans come to think of him as a centerfielder. It may be wrong to speculate that there's a chance McLouth would start in centerfield, no matter how much center he plays this month.
Same question, put another way: is McLouth competing with Duffy for a roster spot, or is he competing with Jody Gerut?
If Duffy's a lock to make the team and lead off, I hope he gets it together soon. He's striking out in about one-third of his ST at-bats.
