Altogether, as a rookie he compiled a 6–4 win–loss record, allowing 68 hits (including eight home runs) in 75⅓ innings pitched; he had the same number of walks and strikeouts (45).

His struggles continued during the 1997 minor league campaign, with his earned run average ballooning to 7.84 in 23 games pitched.

But Brewington lowered his ERA to a respectable 3.84 and earned a promotion in 2000 to the Indians' Triple-A affiliate, the Buffalo Bisons of the International League.

Brewington won his three decisions with Cleveland, with no losses, but allowed 56 hits and 19 walks in 45⅓ innings pitched (he struck out 34).

Granted free agency at the end of the 2000 season, Brewington signed with the Minnesota Twins, but never returned to the Majors.
