Deadline news, July 29: White Sox, Rays chase Nationals' Dunn
• The White Sox and Rays are among the teams talking to the Nationals about slugger Adam Dunn. The belief is the Nats are looking for prospects and could send them to Arizona for pitcher Edwin Jackson. Washington is believed to have asked Chicago for either Gordon Beckham or a tandem of Daniel Hudson and Dayan Viciedo.
• The Rangers' talks for the Marlins' Jorge Cantu heated up Thursday, and, according to the Associated Press, the deal was announced after the Marlins' day game with the Giants. The Rangers sent Double-A right-handers Evan Reed and Omar Poveda to Florida.
• The Rangers tried hard to get Roy Oswalt from Houston, and Oswalt wanted to go to Texas. Texas remains interested in Prince Fielder but won't do it unless they get a lot of money from Milwaukee, which limits their chances.
• The Rockies may consider selling now that they are 51-50 and nine games out in the AL West entering Thursday afternoon's game. Relief pitchers Joe Beimel and Randy Flores are possibilities to go.
• While Miguel Tejada has come up as a possibility for St. Louis, the Cardinals appear to be satisfied that David Freese will be back by mid-August. They may consider middle infielders who can provide more offense than they're getting there, though.
• The Blue Jays asked the Mets for top outfield prospect Kirk Nieuwenhuis plus another prospect in exchange for reliever Scott Downs. The Mets don't want to give up Nieuwenhuis, a 22-year-old outfielder at Double-A who is batting .290 with 16 home runs and 58 RBIs. Toronto wanted top catching prospect Jesus Montero from the Yankees, and either of two prospects -- pitcher Casey Kelly or shortstop Jose Iglesias -- from the Red Sox.
