The Bucks found salvation in Game 3, riding a big-time performance from Giannis Antetokounmpo to success. He reached historic levels with more than 40 points and 10 rebounds, and Antetokounmpo was the key to Milwaukee's dominance near the rim. The Bucks throttled the Suns in second-chance points by a 20-2 margin, and they had a 54-40 edge in points in the paint.

Phoenix has still out-scored Milwaukee for the series, in part due to their excellent shooting. The Suns have a 58 percent true shooting mark through three games, even with Devin Booker struggling. Booker has been their leading scorer, averaging more than 26 points per game in the playoffs, and the Suns can rely on him for an uptick after a down performance in Game 3.
