Bruce Bochy is a funny guy. It's an under-the-radar funny, something that doesn't always come across in his interviews. While I'm sure he doesn't care what internet nerds think about baseball, there's at least a 1% chance that he made this lineup just to mess with nerds from here to the forums at sfgiants.com.
Tejada - SS
Sanchez - 2B
Huff - RF
Posey - C
Burrell - LF
Belt - 1B
DeRosa - 3B
Rowand - CF
Cain - P
The certified Occam's Razor, most likely explanation for this lineup: to mess with "Moneyball"-loving nerds. Or maybe it's to get Tejada to work the count consciously -- to slow down his overanxious approach by making him focus on getting on base. That would actually be a fair reason. Whatever the logic, you will watch Tejada bat as much, if not more, than any other hitter on the Giants today. Enjoy.
