Treanor is expected to go on the DL on Tuesday, and the team is expected to purchase the contract of John Baker from Triple-A Albuquerque, with Paul Hoover and Baker in line to split catching duties.
Even before Treanor's injury, the Marlins were eying veteran catching help. Names to watch are David Ross (Reds), Miguel Olivo (Royals) and Yorvit Torrealba (Rockies). Nationals veteran Paul Lo Duca doesn't appear to be in the mix.
As for the Dodgers, they've scouted Pittsburgh's veteran shortstop, Jack Wilson, and, according to one industry source, are considering Toronto's David Eckstein, who helped the crosstown Angels win a World Series in 2002 before going on to another World Series title with the Cardinals two years ago.
But there seems to be no sense of urgency to make a deal.
The Pirates do not have an heir apparent for Wilson, and in any case, the discussions apparently are not close.
Dodgers general manager Ned Colletti has said that the organization would consider dealing for a shortstop more than they normally would, since the need is so great. On the other hand, the Dodgers intend to give Nomar Garciaparra, fresh off the DL, a chance to show what he can do at the position before moving forward on any outside options.
Wilson is being paid $6.5 million this season, he will make $7.25 million next season and he has an $8.4 million option for 2010. Eckstein signed a one-year deal for $4.5 million during the winter and can be a free agent after this season.
The Cubs continue to look for pitching, just as they were before the Brewers secured Sabathia's services. Oakland's Rich Harden is believed to be No. 1 on the Cubs' wish list now that Sabathia is off the market.
The A's have tremendous leverage in any talks involving Harden, on whom they hold a $7 million club option for 2009 (without a buyout), so they're asking for a return package similar to the six-player haul they got from the Diamondbacks in the offseason deal that sent Dan Haren to Arizona. But Harden is viewed as a significant injury risk, as he's been on the DL six times since the start of 2005, and the Cubs are unlikely to pony up a Haren-type price for him.
