I screwed up in my previous post. The teams ranked with or behind Houston in OBP were the Nationals, Mets and Giants, not the Nationals, Dodgers and Giants.
Here's the leader board again, but we'll throw in the White Sox, Tigers, Royals and Mariners, who also finished tied or below the Astros in OBP:
Sexson, Sea, 121
Wright, NY, 102
Ensberg, Hou, 101
Konerko, Chi, 100
Floyd, NY, 98
Wilson, Col, 90
Ibanez, Sea, 89
Monroe, Det, 89
Everett, Chi, 87
Beltre, Sea, 87
Dye, Chi, 86
Brown, KC, 86
Sweeney, KC, 83
Berkman, Hou, 82
Feliz, SF, 81
