Within hours after David Wells cleared waivers and became a free agent Thursday, the Dodgers and the Rockies were the first teams to express interest in possibly signing the left-hander. Wells was cut free by the Padres last week, after going 5-8 with a 5.54 ERA. Gregg Clifton, his agent, has made it clear that Wells would like to pitch for a contender. The Dodgers have been looking for pitching, in the aftermath of a series of injuries to their starting pitchers, including Jason Schmidt and Randy Wolf. The Rockies have recently lost starters Rodrigo Lopez, Jason Hirsh and Aaron Cook to the disabled list.
