You must be in a small league, because you have a solid team of hitters and pitchers.
I would strongly consider grabbing Bedard. When healthy last year he was lights out. Plus with Mazzone I think he can only get better.
I would consider sending Padilla to the waiver wire, you already have Millwood for Texas, and with that ballpark set up for the hitter Padilla could get roughed up more than Bedard. My other thought was to dump Marquis, but St. Louis provides good run support and he should get some cheap wins.
