Snell was signed by the Orioles as an amateur free agent in September 1976, right after the completion of that year's Minor League season.

He played his first professional season with their Class A-Advanced Miami Orioles in 1977, and split his last season with the Class A-Advanced Miami Marlins and the Cincinnati Reds' Double-A Chattanooga Lookouts and Triple-A Nashville Sounds in 1988.

He threw a total of 7+2⁄3 innings that season, giving up only 2 earned runs and striking out seven.

Snell finished his major league career with a 7-6 record, a 3.29 ERA, 5 saves, 96 strikeouts, and a 1.31 WHIP.
