Pistons big man Ben Wallace has a way of putting a damper on Chris Mihm coming-out parties.

Last season, the 7-foot Mihm played center for the Cavaliers at Detroit in his first NBA preseason game. Wallace frustrated him to no end. In Tuesday's preseason opner at Detroit, Mihm debuted at a new position: power forward. Once again, he ran into the 6-9 Wallace, who guards power forwards, centers and small forwards with equal efficiency.

Once again Wallace rattled Mihm. In a 101-77 Pistons win, Wallace had 10 rebounds and five blocked shots.
