Despite widespread speculation, the Los Angeles Dodgers are not in active talks with the Houston Astros about pitcher Roy Oswalt, who let it be known publicly last week that he wants out of the city where he has spent his 10-year major league career. A source with knowledge of the situation, speaking on condition of anonymity, said Tuesday that despite Oswalt's request, the Astros aren't looking to trade the right-hander and three-time All-Star at this point. But that could change as the summer moves along and the July trade deadline nears, especially if the Astros continue to languish in the National League Central cellar. While the Astros are not shopping their ace, Fox Houston reported on Tuesday that Rangers president Nolan Ryan reached out to Houston to express interest in Oswalt. Oswalt has about $28 million left on a five-year, $73 million contract he signed before the 2007 season, including the $2 million buyout on his $16 million club option for 2012. http://sports.espn.go.com/los-angeles/mlb/news/story?id=5220359
