Wily Mo Pe?a has cleared trade waivers, according to a major league source, meaning the Red Sox can negotiate a deal for him with any team. "I want to be traded," Pe?a said yesterday. "I want to play. They know I want to play. I'm surprised I wasn't traded before the deadline." Pe?a is batting .223 with just 5 home runs and 16 RBIs after going 1 for 1 in last night's 10-4 loss to the Angels, not the kind of numbers that are going to cause contenders in search of a bat to fall over each other. But because he's just 25, there are still teams that believe -- as the Red Sox did a year ago when they acquired him from the Reds for pitcher Bronson Arroyo -- that there remains a great deal of untapped potential.
