FOX Sports' Ken Rosenthal reports that Roy Oswalt will make a pro-rated portion of $2.3 million if the Rockies add him to the major league roster. Oswalt would also receive a $400,000 bonus if he is added to the roster. The veteran right-hander could make more with incentives, including $1.35 million for 18 starts and $1.25 million for 110 innings pitched. His contract has out-clauses on June 18 and June 28.
