With Detroit, he was a reliable starter in the rotation for years, consistently giving his team six and more innings each start. This complemented Jack Morris and Dan Petry, who were power pitchers and considered the aces. His 17 wins in 1984 were important in the Tigers' run to their world championship. (Morris won 19, Petry 18 that year.) He won one game each in that year's ALCS and World Series. That year, he also started his season going 6-0. This was not duplicated by a Tiger pitcher until 2007, by Jeremy Bonderman.
