AUBURN HILLS, Michigan (Ticker) -- After making good on Rasheed Wallace's victory guarantee in Game Four, the Detroit Pistons look for a 3-2 series edge over the Indiana Pacers in the Eastern Conference semifinals on Tuesday.

Wallace backed up his guarantee by scoring 17 points, grabbing 12 rebounds and setting a career high with five blocked shots as the Pistons defeated the Pacers, 89-76, on Sunday.

After trailing 9-2, Detroit scored 19 of the next 20 points in an eight-minute stretch of the first quarter, while the Pacers missed 13 consecutive shots.

Chauncey Billups scored 29 points and Richard Hamilton added 13 for the Pistons, who have averaged more than 85 points in the first four contests.

Stephen Jackson scored 23 points, Jamaal Tinsley added 17 and Jermaine O'Neal 10 with 13 rebounds for Indiana, which shot just 37 percent (26-of-70), including 3-of-19 from the arc.

O'Neal has made 6-of-26 shots in the past two games and Reggie Miller scored only seven points in 36 minutes Sunday.

Indiana has failed to reach 80 points in the last two games and has shot less than 40 percent from the floor in seven of its 11 playoff contests.

The series moves to Indianapolis for Game Six on Thursday.
