DALLAS (AP) — Mavericks coach Rick Carlisle was looking for any solution he could find to turn around his team's sputtering offense.
Then seldom-used guard Rodrigue Beaubois gave Dallas the scoring punch it needed to turn away the Cleveland Cavaliers.
Beaubois scored 18 points off the bench and keyed a fourth-quarter run to lead the Mavericks past the Cavaliers, 96-86 on Friday night.
Beaubois scored nine points and added three assists in the fourth quarter. The French guard had played just 33 minutes since Feb. 22 and totaled nine points in the team's previous five games.
"We have to make sure that everybody's ready," Beaubois said. "Even if you don't play, the next game maybe you're going to get in. So you have to be ready to contribute and to help the team win."
Dallas had a sluggish start after losing 92-91 Thursday night in San Antonio. The Mavericks hit only 7 of 21 shots in the first quarter and trailed by 11 early in the second.
Carlisle then turned to Beaubois and his mates off the bench. The Mavericks reserves outscored their Cavaliers counterparts 60-19.
It was Beaubois, though, who provided most of the offensive output for the bench with his most productive game since scoring 19 against the Spurs on Jan. 25. He scored seven points in a 17-4 run that gave Dallas the lead for good in the fourth quarter.
"(Beaubois) had his best game of the year and it was certainly his most timely," Carlisle said. "We knew we were going to have to go deep to be able to win."
Cleveland's Dion Waiters had 21 points and Shaun Livingston chipped in with 13. The Cavaliers, who were playing their second game without All-Star Kyrie Irving, were outscored 29-18 in the fourth quarter.
The Cavaliers went nearly five minutes without a field goal at one point in the fourth. They also turned the ball over six times in the final quarter.
"I thought we got a little upset at ourselves at the way we were defending," Cleveland coach Byron Scott said. "We kind of let that affect us on the other end."
Beaubois scored to put the Mavericks up 71-70 early in the fourth. He found Brandan Wright for a layup and then drained a 3-pointer to extend Dallas' advantage to 80-72.
Darren Collison and Wright had baskets to finish off the 17-4 run, putting the Mavericks up 84-72 with 6:17 left.
The 6-foot-2 Beaubois punctuated his game later in the fourth with an emphatic dunk on a baseline drive.
