His best postseason series was his first, against Oakland. He started 2 games out of the 5, winning both with a 1.54 ERA. Radke only gave up 1 run in the deciding game of the series before the 5-1 Twins lead was almost squandered in the 9th, when Eddie Guardado gave up 3 runs. But the Twins won 5-4 and advanced to the 2002 American League Championship Series. He would go on to lose the only game he pitched against the Angels, but shut them out for the first 6 innings of that game. In the end, the Twins bullpen and offense failed and they lost 7-1 and lost the series 4-1.
