Miami Heat star Jimmy Butler just has that clutch gene. With his team down by two points with under 10 seconds left, Butler squared up with Giannis Antetokounmpo on the perimeter. With the clock winding down, he drove past the Greek Freak and converted a tough layup at the buzzer to send Game 1 to overtime. Take a look:

Absolute ice in Butler's veins. It wasn't the most electrifying day from a scoring standpoint for the Heat veteran, dropping just 17 points. But, he also dished out eight assists and grabbed 10 boards as Miami has gone toe to toe with the Bucks.

The Heat struggled from the field, but they were also lethal from downtown thanks to seven three-pointers for Duncan Robinson. Antetokounmpo also helped their case by missing numerous free throws.

In the end, though, Khris Middleton's dagger with just seconds remaining in OT gave Milwaukee the victory over Miami by a score of 109-107. Robinson led the Heat on the day with 24 points.

It was definitely a thrilling opening game to the series and it's clear: the Miami Heat will not be going down without a fight in this first-round matchup. Mike Budenholzer's team will certainly have their work cut out for them.
