Are they out of pitchers, or just bored, or what?
And who is Alderson?
They weren't out of pitchers but most of the relievers are probably unavailable. I don't know who is going to replace Balester in their rotation. They have Martis-Detwiler-Estrada-Ramirez.
Alderson was the Giants 1st round (22nd overall) pick in the '07 draft out of HS. He's a big guy (6' 6", 217 lbs).
He's only 20 but he's already pitching in AA. He has a 3.47 ERA this season.
