Those teams fit in with the Dodgers' pursuit of pitching, with Seattle's Cliff Lee, Houston's Roy Oswalt and Arizona's Dan Haren some of the top names on the trade market.
"Unless something knocks your socks off or something makes sense, I think pitching is the area probably -- starting and relieving," manager Joe Torre said Tuesday. "Whatever will tighten up what we have now."
With their payroll down the past two seasons, the Dodgers likely would only be able to acquire one premier player, most likely a pitcher. A baseball source said no deals appear imminent, with the non-waiver Trade Deadline on July 31.
Lee is in the last year of his contract, while Oswalt, on a 5-year, $73 million deal, is to make $16 million next season. Oswalt has a team option for 2012, with a $2 million buyout -- making the minimum he would be owed for just next season's service $18 million.
"I know [general manager Ned Colletti] has been exploring, and we've done it the last couple years, and my guess is we'll get some help," Torre said.
