Boston can thank Terry Rozier for helping secure Game 1 against the Bucks.
The former Louisville Cardinal hit a big three with seconds remaining to put the Celtics up with barely any time on the clock.
Khris Middleton then hit the tying three for the Bucks to send the game into OT.
In overtime, Rozier added some late free throws to help put the game on ice for the Celtics.
