Around the 10-minute mark of the second quarter, the Thunder forward ran to the three-point line to set a screen for Jeremy Lamb. Perkins then rolled to the basket, received a pass from Lamb and flushed the ball through the rim with two hands as Giannis Antetokounmpo attempted to block him.
The jam fired up Oklahoma City's bench.
Entering Tuesday, Perkins was averaging five points and five rebounds over seven games. The Thunder -- playing without stars Kevin Durant and Russell Westbrook -- are 2-5 this season, while the Bucks are 3-4.
Oklahoma City trailed Milwaukee by three points at halftime.
