Yesterday, Nick Cafardo of the Boston Globe wrote that "the Brewers may be emerging in the hunt" for free agent Pedro Martinez. However, talking to MLB.com's Adam McCalvy, Brewers GM Doug Melvin said he's never spoken to Pedro's agent.
Cafardo learned that the Dodgers haven't been involved on Pedro since the offseason. He then speculated in his article on the Mets, Rangers, Nationals, Blue Jays, Astros, Rockies, A's, Orioles, Indians, and Pirates. T.R. Sullivan informed us today that the Rangers "do not expect to get involved" with Pedro. The Nationals are known to have mild interest. And here's a Ken Rosenthal's take from Thursday (he downplayed the Angels, Indians, Dodgers, and Mets as suitors).
Bottom line: the Nationals are the only team admitting current interest, and acting GM Mike Rizzo is wary of the price.
