Jazz rookie point guard Trey Burke scored 11 points on 5 of 15 shooting, which was an improvement over Monday's 1 for 12 performance. Burke also had 2 assists.
Alec Burks led the Jazz with 18 points, while Jeremy Evans added 10 points and 8 rebounds. Rookie center Rudy Gobert added 4 points and 7 rebounds.
Five Rockets recorded double figures en route to their second victory in summer league play.
The Rockets jumped out to an early lead and were never really in jeopardy the entire game, using a strong second quarter to take a double-digit lead into halftime, 43-30. Although the Jazz outscored the home team in the fourth, Houston held on to nearly a 20-point advantage for most of the second half.
Utah was plagued by turnovers and poor shooting, turning over the ball 18 times en route to 28 Houston points while shooting just 37.7 percent from the floor.
Utah (1-1) resumes summer league play Wednesday, taking on the 0-2 Brooklyn Nets.
