The Christmas Day dunk came with about five minutes remaining in the first quarter of the 117-96 victory on Tuesday at Vivint Smart Home Arena. Utah led 14-12 when Kyle Korver intercepted a pass intended for Damian Lillard.
Korver then threw a pass to Jae Crowder. The veteran forward took a dribble before spotting Mitchell running toward the rim. Crowder launched a half-court pass, finding Mitchell as he jumped through the paint. Mitchell snagged the ball and smashed it through the rim, giving the Jazz a four-point edge.
"The catch was easy," Mitchell told reporters.
"It was the turning around and trying to find the rim. I didn't know where I was. I didn't know if I was going to airball the dunk, dunk nothing. So it was kind of like praying to God that it was right there and it was. A Christmas gift from God for sure."
Mitchell led the Jazz with 19 points. Lillard netted a game-high 20 points for Portland. The Jazz host the Philadelphia 76ers at 10:30 p.m. Thursday in Salt Lake City.
