Brandon Jennings scored 20 of his 30 points in the third quarter, leading the Milwaukee Bucks to a 117-90 victory over the Detroit Pistons on Tuesday night.

Mike Dunleavy had 17 points and Monta Ellis added 14 for the Bucks, who led by as much as 29 points.

Rookie Andre Drummond had 18 points and 18 rebounds for Detroit, while Greg Monroe scored 14 points. Drummond became just the second teenager to have an 18-18 game since 1985-86, joining Dwight Howard.

The Pistons led by 15 points late in the first quarter, were outscored 78-40 over the next 25 minutes.

Milwaukee had a 33-14 scoring edge in the second quarter, including Samuel Dalembert tipping in a missed free throw that had been taken with 0.1 seconds left.

Things got even worse in the third quarter, as Jennings — considered a possible replacement for the injured Rajon Rondo at the All-Star game, hit five 3-pointers. He accounted for all of the scoring during Milwaukee's 16-0 run that was capped by four 3s, pushing the Bucks' lead to 85-56 with 3:42 remaining in the period.

Detroit's defensive effort disappeared at that point, leading to a particularly ugly sequence in the fourth. Dalembert got open for back-to-back uncontested dunks in a halfcourt set, with John Henson making it three in a row on the next possession.

NOTES: Dunleavy had a four-point play as part of his 14-point second quarter. ... The Pistons had beaten Milwaukee in both meetings this season. ... The Pistons honored NASCAR Sprint Cup champion Brad Keselowski at halftime. Keselowski is from Rochester Hills, only a few miles from the Palace. ... Howard had three games of at least 18 rebounds and 18 points at the age of 19.
