I would do it, but make him give you a decent pitcher, too. You need offense and Giles will give you're BA a big boost, (especially since you have Dunn) and he'll hit HR's.
As it is, this is basically Giles for Hudson. Garcia has pitched awful all year long and so far there's no reason to think he'll snap out of it. He is waiver wire material this year. You should be able to get a little more for Giles. At least a decent closer, but maybe a decent starter..
Bluto: Over? Did you say over? NOTHING is over until WE decide it is! Was it over when the Germans bombed Pearl Harbor? HELL, NO!
Boon: Forget it, he's rolling.
