As a rookie, he was 4-3 with a 2.55 ERA for the GCL White Sox. He went 7-11 with a 3.44 ERA for the 1988 South Bend White Sox. The big right-hander led the Midwest League in both hits allowed (206) and hit batsmen (19). In 1989, he improved to 14-8, 3.39 for the Sarasota White Sox, with only 32 walks in 164 2/3 IP.

He got into 11 games for the 1991 Vancouver Canadians (0-2, 7.81, 44 H, 24 BB in 27 2/3 IP) before finishing the year as a coach back with Sarasota.

In 2017, he was named bullpen coach of the Chicago White Sox, replacing Bobby Thigpen. In 2018 his title changed to assistant pitching coach though it appears he functioned as a bullpen coach in that first year. He kept the title of assistant pitching coach through 2020. His title reverted back to bullpen coach for the 2021-2023 seasons, after which he was let go.
