Romero sues supplement maker

Suspended Phillies pitcher J.C. Romero has filed suit against a nutritional supplement manufacturer alleging an unlisted ingredient in one of its products caused him to test positive for a substance banned by Major League Baseball.

Romero, who was suspended for the first 50 games of the 2009 season by MLB, claims he tested positive for steroids last August because a supplement he was taking, 6-OXO Extreme, did not specify it included androstenedione.

He filed suit Monday in Camden County, N.J. seeking punitive and compensatory damages.

Romero also named as defendants the corporate owners of two nutritional stores where he purchased 6-OXO Extreme, alleging sales clerks assured him it would not cause a positive test for a banned substance.
