This righty (1,010 games) from Santurce, Puerto Rico, broke in with the 1991 Chicago White Sox. In 1997 he, Wilson Alvarez, and Danny Darwin all were dealt to San Francisco in the "White Flag Trade." In 1999 he saved 43 games for the Tampa Bay Devil Rays (who only won 69 games). His Wikipedia page refers to him as "(relief pitcher)" to distinguish him from the player previously known as Fausto Carmona.
