The five foot eleven right hander was signed by his uncle one time Met; Jesus Alou, then a scout, in 1985 for the Montreal Expos. He began as a starting pitcher getting converted to a reliver on the minor leagues. In 1989 he was ranked as the 35th best prospect in baseball by Baseball America.
His bebut came with the Montreal Expos in 1990, where he would spend seven seasons though 1996. He would play under manager Felipe Alou, his uncle & as a team mate to his cousin Moises. In 1992 he was used him in 62 games, with 100 innings pitched, as he went 7-1 with ten saves and posted a spectacular 1.43 ERA for the second place Expos.
In the strike shortened 1994 season, the Expos were in first place but no post season games were played. That yeat he recorded 16 saves (8th in the NL) with a 3.32 ERA.
Over the next two seasons he recorded thirty plus saves, coming in the league's top ten in that department both seasons.
He was as high as 5th in saves in the NL in 1996. The Expos were not going to able to sign him for money reasons going into 1997 and he signed as a free agent with the Chicago Cubs.
