Oswalt to Mets: highly unlikely

A source familiar with the Houston Astros' thinking doesn't believe right-hander Roy Oswalt will end up with the Mets, assuming he does get traded.

"They may sniff, but have no chance," the source said regarding the Mets.

Oswalt, 32, has a no-trade clause and has never shown an affinity for New York. He's earning $15 million this season, $16 million next year and has a 2012 option with a $2 million buyout.

The three-time All-Star is 1-2 with a 2.37 ERA in three starts this season.
