The Rockies have placed Brian Fuentes and Willy Taveras on waivers. Ken Rosenthal has the story here. According to him:
If either or both are claimed, the Rockies will have 48 hours to work out a trade with the claiming team or teams. If either or both clear waivers — which is unlikely — they can be traded to any club.
The Dodgers, who own the worst record of any National League contender, will get the first crack at claiming Fuentes.
He goes on to say that Tito makes sense for Dodgers because Takashi Saito is hurt. He also speculates that the Mets and/or Phillies might be interested in Taveras.
