Mathematicians at MIT were hovering over their computers lateinto Sunday night trying to calculate how the Giants could have 10 hits and a walkwith nobody out in the fifth inning with only one run, and why ittook three hits to get that man home from second base. That is your 2011 Giants offense, and it is hard toimagine a vast improvement down the stretch. And yet, the Giants remain in first place in aweak NL West after a 3-1 victory over Philadelphia because theyhave pitchers such as Tim Lincecum.
