Multiple teams are making a late run at the Philadelphia Phillies with offers for pitcher Cliff Lee as Wednesday's trade deadline nears, baseball sources told ESPN.com Friday. Although Phillies general manager Ruben Amaro Jr. declined to address the extent of other teams' interest in Lee, he said he's keeping an open mind on Lee and numerous other Philadelphia players who might generate interest at the deadline. "I never put any real absolutes on anything," Amaro said by phone Friday. "Although we don't have any desire to move a guy like that because we view him as someone who will be key to our future, I am a businessperson as well and I'll be a good listener. "I can't sit here and say I'm not going to trade Chase (Utley), or Cliff, or Michael Young or Chooch (Carlos Ruiz), or any of these guys. Some guys are less tradable than others. But I think I owe it to us as an organization to listen. If teams are going to come at us and suggest things, I'm not going to turn off the faucet and stop listening to them." Lee has been scratched from Saturday night's start at Detroit because of a stiff neck, and will be replaced by left-hander Raul Valdes, who has gone 1-0 with a 7.59 ERA in 11 relief appearances this year.
