Good article on Yahoo sports about how the Yankee, Red Sox and tigers lineups compare. The end result is the following;
Expected runs/game for everyday lineups
Best Likely Lineup Worst
Yankees 6.35 6.20 6.02
Red Sox 6.10 5.95 5.71
Tigers 5.97 5.86 5.60
The flaw with the article is the projected Yankee lineup which had both Matsui and Giambi in it. While the Big G probably will get a bunch of ABs his inability to play the field guarantees that he and Matsui won't play together for a significant amount of time.
