We've already checked out some Giants and Rockies rumors today, so let's look around the rest of the NL West…
- The Dodgers won't trade top pitching prospect Zach Lee for a rental player like Ryan Dempster, reports Ken Rosenthal of FOX Sports (Twitter link). We heard earlier today that Los Angeles had made the Cubs an offer for Dempster.
- Though the Diamondbacks and Pirates have had trouble connecting on a trade match for Justin Upton, the outfielder remains "at or near the top" of Pittsburgh's search for a hitter, tweets Jon Paul Morosi of FOX Sports.
- The Diamondbacks have signed 16-year-old Dominican outfielder Ismael Pena, reports Ben Badler of Baseball America. Badler describes Pena as "a 6-foot-3, 175-pound lefty with a sound swing, a good approach and a hit-first, power-second profile. He's an average runner with a 45 to 50 arm on the 20-80 scale."
- Huston Street was "aggressively" pursued by the Mets last winter, a source tells Andy Martino of the New York Daily News (Twitter link), but through the Mets are searching for bullpen help now, they don't think the Padres will move the closer. We heard earlier today that the Padres were looking to propose long-term extensions to Street and Carlos Quentin before the trade deadline.
- Street and Chris Denorfia have drawn more trade interest than Quentin, reports Bill Center of the San Diego Union-Tribune.
- Also from Center, the Pirates and Orioles are "among the teams pushing hardest" for Chase Headley. Center added the Mariners to the long list of Headley's suitors. The third baseman himself says he has heard "between six and 10 teams" have shown interest.
