He appeared in 205 major league games and had a lifetime record of 12–7 (.632 winning percentage) with 168 strikeouts, 70 games finished and 8 saves. His lifetime earned run average was 3.65 for an Adjusted ERA+ of 110.

Dewey was involved in a notable controversy on July 28, 1996, when he refused to participate with his teammates in a pregame ceremony intended to support research of a cure for AIDS. As part of "Until There's A Cure Day", members of the Giants wore AIDS awareness ribbons on their uniforms and stood in a group shaped like that symbol during speeches by Giants owner Peter Magowan and San Francisco Mayor Willie Brown. Dewey refused to take the field for the ceremony, and he wore his ribbon sideways (which would have resembled the Icthys, a popular symbol meant to represent Jesus in Christian culture). He cited religious reasons for his refusal, stating that the ceremony was "against Christian principles" and voicing the belief that homosexuality is a sin.
