Brad Penny isn't scheduled to clear waivers until early next week, but we've already heard that several clubs are interested in picking him up for the stretch run. The Oakland A's are one of those teams, but Susan Slusser of The SF Chronicle says that the team believes Penny "might be claimed on release waivers and he likely would accept because he is close to getting some bonuses."
Meanwhile, ESPN's Buster Olney hears that in all likelikood, Penny's decision will come down to whatever team appears to have the best chance of winning a championship. Pitching for a contender would allow him to "better set himself up for his impending free agency." This is just my belief, but if he wants to boost his stock prior to free agency he's best off heading back to the National League.
