"It (doesn't) play out the way we always picture it, but tonight we just played extra, extra hard down the stretch to get a win," Ellis said.
Ilyasova had 20 points and 11 rebounds for Milwaukee. Jennings added 15 points and 14 assists.
Afflalo scored 24 points and Harkless had a career-high 23 for the Magic. Nikola Vucevic added 20 points and 15 rebounds in the loss.
"In the fourth quarter we didn't defend like we did the first three quarters," Vucevic said. "We played well for most of the game, but at the end of the game Monta Ellis made some huge shots, some tough shots. We didn't make the right adjustments. We didn't defend it right. They got back into it and got the win."
Orlando outscored Milwaukee 62-40 in the paint.
"We were just moving the ball and I had a chance to get a lot of easy buckets. My teammates were able to find me," Vucevic said.
Tobias Harris, traded by the Bucks to Orlando in a six-player deadline deal last month that brought Redick to Milwaukee, gave a wry smile when asked if he had seen Ellis have an outburst like he did in the fourth quarter on Sunday.
"Not that many 3s, to be honest," Harris said. "He was hot and they made some real tough shots. They made shots that were contested and shots where they had a lot of bodies around them. (Ellis) is a big-time player and he makes those plays."
The Bucks began the game by missing 11 of their first 13 shots while the Magic failed to connect on nine of their first 12 attempts. Orlando improved its shooting and led 25-18 after the period.
The Bucks' shooting woes continued in the second quarter. Milwaukee finished the first half shooting just 30 percent and trailed 54-44. The Bucks opened the third on a 7-0 run, but the Magic rebuilt the lead to 13 late in the quarter. Orlando was up 81-70 going into the fourth.
"You have to give Milwaukee credit for continuing to play throughout the course of the game," Orlando coach Jacque Vaughn said. "Our focus and our intensity has to be the same throughout. We will all do some self-examination. I will see what I could have done better to put our squad in a better position to win."
NOTES: The Bucks improved to 8-0 at home on St. Patrick's Day. ... Magic rookie forward Andrew Nicholson returned after missing Friday night's game and not practicing Saturday while quarantined because of illness. ... Milwaukee's Luc Richard Mbah a Moute missed his fourth consecutive game with a turf toe injury. Marquis Daniels, who scored 14 points against Miami on Friday night, started in his place. ... The rare noon start required the teams to alter their routines. "It's just different. Do you go to bed earlier? When do you wake up to eat? How much do you eat? Routine-wise, it throws you off," Vaughn said.
