The Miami Heat and the Boston Celtics opened the Eastern Conference finals with a bang Tuesday.

Or maybe it was a Bam.

Heat All-Star Bam Adebayo secured Miami's Game 1 victory with a thrilling block of Celtics forward Jayson Tatum in the closing seconds of overtime. It capped a frantic final stretch of the fourth quarter and overtime that saw clutch buckets from Tyler Herro, Jimmy Butler and Kemba Walker.

NBA players and celebrities took to Twitter following Adebayo's highlight block and Miami's Game 1 win.

Miami looks like it hasn't lost a step after ousting the NBA-best Milwaukee Bucks one week ago. And if Tuesday's Game 1 is any indication, we're in for an epic series between the Heat and Celtics.
