"John Smoltz's brief career with the Red Sox is over.

Smoltz has refused the option of an assignment to the minor leagues, leaving the Red Sox with the option of either trading him or releasing him.

A trade is possible because Smoltz has cleared waivers, and the Dodgers are among the teams showing interest. But any deal would require a significant financial component due to the incentives in Smoltz's contract.

Smoltz, 42, receives about $35,000 for each day he is on the active roster and other appearance-based bonuses. He also receives a $500,000 bonus if he is on the active roster and not the disabled list on the last day of the season and a $500,000 bonus if he is traded."
