Calvain Culberson will be in his fifth season as a full-time assistant coach at AASU, after completing an eight-year professional baseball career. Calvain is no stranger to Armstrong Atlantic, having played for the Pirates from 1985-1988, and having assisted coach Roberts in a part-time role during his professional career.

Calvain's coaching role at AASU includes working with the outfielders and pitchers, and assisting with baserunning and hitting instruction.

Culberson finished his pro career in 1995 at Pawtucket, a triple-A affiliate of the Boston Red Sox. He had joined the Red Sox organization as a free agent after having pitched at Double-A Chattanooga and Triple A Indianapolis in the Cincinnati Reds farm chain. Calvain began his pro career in 1989 in the Atlanta Braves farm system, where he hit .313 in his first season, before changing positions and becoming a pitcher. During his pro career, Calvain was a member of two championship teams, in 1990 (Charleston, W. Virginia of the South Atlantic League) and again in 1992 (Cedar Rapids, Iowa of the Midwest League).

During Culberson's AASU career, the Pirates posted an overall 181-66 (.733) record, with Calvain hitting in the leadoff spot his final three years. The Rome, Georgia native holds seven school records with the most notable being his 32-game hitting streak (1988) and his 128 career stolen bases.

Calvain was an all-Big South Conference selection in 1986 and 1987 when AASU was playing NCAA I baseball. In his last season with the Pirates he was an AASU co-captain and was chosen as a member of the all-South Atlantic Region team and an honorable mention All-American in NCAA II.

Calvain is married to the former Pamela Johnson of Port Wentworth, an AASU graduate, who works as a System Analyst II for AASU. The couple have a son, Matthew, born March 29, 1998.
