Rudy Gobert made a key rebound and an even bigger dunk with 11 seconds remaining to boost the Utah Jazz to a series-tying 100-99 win over the Dallas Mavericks on Saturday afternoon in Salt Lake City.

Jordan Clarkson led Utah in scoring with 25 points, Donovan Mitchell added 23 points, seven assists and six rebounds, and Gobert finished with 17 points and 15 boards in a game that nearly slipped away.

Luka Doncic, in his first action of the postseason, scored a game-high 30 points with 10 rebounds and gave Dallas a four-point lead with 39 seconds left. Mitchell cut the lead to one with a putback layup and a free throw with 31.2 seconds left after being fouled by Doncic.

The Jazz fouled Dwight Powell with 19.8 seconds remaining, and he missed both shots. Gobert then grabbed the rebound and put Utah up 100-99 with an alley-oop dunk off of a pass from Mitchell. Game 5 will be Monday in Dallas.
