For the third time in four games, North Texas allowed less than 45 points, and the Mean Green won their fourth straight.
"We picked it up on defense after a slow start," Bradley said. "On offense we all executed really well and played a lot better than the last game. "
UNT (6-1) entered Saturday with the nation's best field goal percentage defense, holding its previous six opponents to a combined 30.5 percent. Tulsa (3-5) made just 25 percent of its 44 field goal attempts.
"Defense has been huge for us," said UNT coach Jalie Mitchell. "We've stopped some solid teams from reaching their average, and everyone on our team has bought in to the way we defend."
The Golden Hurricane entered Saturday averaging 62 points. They were without leading scorer Shug Dickson, who is averaging 15 points, and second-leading scorer Kendrian Elliott was limited to four field goal attempts and six points.
The game was close in the first quarter, but an early second-quarter surge by the Mean Green gave them a more comfortable lead. During the second quarter, Bradley scored seven of her 23 points and UNT forced four turnovers, scoring off all of them.
"Terriell has been awesome this season," Mitchell said. "There are times when we need her at the 1, sometimes the 2, sometimes at the 3 and she starts at the 4. It's a great leadership quality and shows the team that she's willing to do whatever is needed for the team to get the win."
The Mean Green built on their lead in the third quarter and pulled away in the fourth when Mims dropped in 10 of her 15 points.
Mims was 4-for-4 from the field in the fourth and made two free throws as she helped North Texas take a lead topping 20 points.
As the Golden Hurricane tired out, UNT's defense stepped on the gas and prevented them from making a field goal in final 5 minutes, 29 seconds.
North Texas takes its four-game winning streak to Indiana at 6 p.m. Tuesday.
