Sporting News (5/22):
Cincinnati has earned contender status more quickly than most expected, and the contracts of Bronson Arroyo and Aaron Harang will come off the books after this season (freeing up money). A rotation of Oswalt, Johnny Cueto, Edinson Volquez, Mike Leake and Aroldis Chapman would be impressive. The Astros are far from eager to have Oswalt haunt them in head-to-head meetings in the future.
John Fay (5/21):
Oswalt makes $15 million this year, $16 million next year, and there’s a club option for $16 million with $2 million buyout in ’13. That’s probably out of the Reds’ price range. But Aaron Harang and Bronson Arroyo, who make similar money, are in the final year of their contracts. I don’t think it will happen. But my guess is the Reds at least look into it.
