Dallas took it to Utah early on, going ahead 22–9 after a Dwight Powell dunk capped an 18–4 run. Charlie Brown Jr. gave the Mavericks their biggest lead, 30–14, with a dunk moments later.
Conley ignited a 9–0 run with a 3-pointer, followed by a pair of free throws, later in the first quarter, and then fueled an 11–2 spurt at the beginning of the second quarter, with back-to-back treys that tied the score at 36.
Utah led 65–63 lead at the break.
After Dallas pushed ahead again after halftime, the Jazz needed a 15–6 run at the end of the third quarter to pull even again at 90.

Dallas wasn’t done, though. Led by a pair of 3-pointers from Brunson, the Mavericks scored eight straight to make it close heading down the stretch.
