Minor Irritation

Okay, I don't understand. Why even pitch to Pujols when first base is open? I mean okay you are up by 2 with 2 outs. One of the best hitters in the league is up. Why not just walk him and face the guy with the injured neck? Pujols has the speed of a crippled hippo so he's no threat on the bases anyways. But Astros will win the next game and erase this minor annoyance. GO 'STROS!!
