Everyone pitched in for the short-handed Bucks, who came in losers of seven of the last eight.
John Salmons added 16 points and tied a career-high with 12 assists for Milwaukee, Brandon Jennings scored 20 points to match his best performance since returning from surgery and Luc Mbah a Moute finished with 13 points and 10 rebounds.
Mbah a Moute did an admirable job trying to slow Clippers' star Blake Griffin, who still finished with 19 points, 12 rebounds and six assists.
The Clippers are 1-6 on this marathon 11-game, 21-day road trip that encompasses the Grammys and the All-Star break.
Delfino hit five of Milwaukee's six 3-pointers in the fourth quarter, including three in a 4-minute stretch as the Bucks used a 14-1 run to take an 85-68 lead. The Bucks shot 11 of 26 from 3-point range and Delfino hit 7 of his 10 attempts from beyond the arc.
The Bucks continue to be hampered by injuries and were without Corey Maggette (back) and Drew Gooden (left foot). They lost Ersan Ilyasova (right eye) early in the first quarter.
Jennings didn't escape unscathed either. He sported a large bandage above his right eye in the third quarter after apparently getting scratched.
Still, Milwaukee blistered the Clippers down the stretch even without Andrew Bogut, who finished with 10 points but fouled out early in the fourth quarter.
Baron Davis scored 22 points and Randy Foye finished with 16 for the Clippers, who fell to 4-21 on the road this season. Both Griffin and Davis provided plenty of highlights.
Griffin hardly flinched when the 6-foot-1, 169-pound Jennings tried to block a dunk attempt on what turned into a three-point play, but Los Angeles failed to extend a 58-57 lead following a layup by Foye.
Jennings was a catalyst.
On one play, Jennings found Mbah a Moute, who flipped a pass around Griffin to Bogut for an emphatic slam that made it 43-30 late in the first half. The crowd booed loudly just before halftime when the Clippers got out on a 2-on-0 fastbreak and Foye took an uncontested layup instead of giving the ball to Griffin for a potential dunk.
But Griffin gave a crowd eager to see his high-flying abilities a show in the final minute when Davis lobbed a half-court alley-oop pass to the former No. 1 overall pick, who slammed it over a helpless Delfino.
Notes: Ilyasova left after being hit in the right eye early in the first quarter. He did not return. ... Jennings scored 11 points in the first quarter and Davis had 11 in the second.
