Pedroia is looking pretty good as his main competitors seem to have leveled off.
1. Quentin is done and likely needed a 40 HR season and a White Sox division crown to win.
2. Hamilton has cooled off considerably and plays for a terrible team.
3. Morneau and Mauer should split up the votes and there is a good chance the Twins do not make the post season.
4. Sizemore plays for a weak team and I doubt you see the MVP and Cy Young come from a non-playoff team.
5. Arod has not had an A-rod-like season.
When you factor in that Pedroia will likely win a gold glove, batting title, score 125-plus runs, hit nearly 20 Hr's, 80-plus RBI's, near 20 SB's, a near .900 OPS... I think he is the clear frontrunner at this juncture.
Also, while Youks may split up some of Pedro's votes, the one consistent player in the Sox lineup all year has been Pedroia. Drew, Ortiz, and Lowell all missed significant time and even Youks has missed somegames in recent weeks. As the Red Sox have distanced themselves from the pack in the Wild Card, Pedroia has been the spark-plug and cornerstone of the offense.
