CLEVELAND -- A Cavaliers lineup that hadn't played together at all this season was good enough to overtake and fend off the Charlotte Hornets on Sunday. And they did it while Kyrie Irving and Kevin Love remained on the bench.

Channing Frye made five of Cleveland's 14 3-pointers in their 100-93 win Sunday over the Hornets, making the Cavs the first team in history to make at least 10 3-pointers in each of their first nine games. Yet coach Tyronn Lue still doesn't think they're playing up to their potential.

"I think we can shoot better," Lue said. "It's been sporadic."

Frye scored 20 points off the bench and LeBron James scored 19 points, grabbed eight rebounds and passed for eight assists. James' 3-pointer in the final minute extended the Cavs' lead to nine and handed the Hornets their second straight loss.

Irving scored 19 points, while Love scored 17 points and grabbed 11 rebounds for Cleveland. Neither star played in the fourth quarter, however, because Lue stuck with a lineup of James, Frye, Iman Shumpert, Richard Jefferson and Jordan McRae.

The Cavs trailed 72-71 entering the fourth, but Shumpert and Frye made 3-pointers to give Cleveland the lead. Frye's second 3-pointer of the quarter extended the lead to 89-80 with 5:43 to play, and he followed it up with a mid-range jumper to push the lead to double figures.

Eleven of Frye's 20 points came in the fourth quarter. Shumpert matched his season-high with 15 points off the bench.

"Shumpert shot the ball well, which you're going to have to live with on their team," Hornets coach Steve Clifford said. "But Frye can't get those shots if you're going to win. He's a professional scorer and has been for a long time. LeBron kept looking for him, and we didn't react."

Kemba Walker scored 21 points for Charlotte, extending his streak to eight straight with at least 20 points. Michael Kidd-Gilchrist returned from a strained back to score 11 points and grab 10 rebounds. After starting the year 6-1, the Hornets have lost their last two games to the Raptors and Cavs -- the two teams considered the best in the East after meeting in the conference finals last season.

Charlotte went cold in the fourth, making just 8 of 24 shots. Walker was so frustrated by the loss, he sat in front of his locker in his uniform shorts for more than 20 minutes.

"We just let the game get away from us," he said. "They made some great plays and just found guys when they needed to. They were just making big plays down the stretch."

McRae was getting a chance to play for the Cavs because J.R. Smith sat out with a sore right ankle he suffered during Friday's win at Washington. That moved Mike Dunleavy into the starting lineup and moved McRae into the rotation for at least one night. Lue liked the rhythm the reserves played with and stuck with them even after the Hornets pulled within four in the final two minutes.

"Our second (unit) guys did a great job," James said. "It was good we were able to close the game out."

The Cavs broke the 3-point shooting record set by the Houston Rockets, who made at least 10 3-pointers in their first eight games to open the 2014-15 season. The Cavs began the day ranked second in the league in 3-pointers made, averaging 13.1 per game.

"I think we're hitting the open man, we're making good cuts," Frye said. "I think the fact we're constantly attacking the rim, guys help, we kick out. We have maybe five 40 percent 3-point shooters on our team right now. We're just passing to the open guy, the ball follows energy, so we're just playing good ball."

NOTES: Cavs G J.R. Smith missed the game with a sore right ankle, which he injured in Saturday's win at Washington. The injury isn't considered serious. Mike Dunleavy started in his place. ... Smith is three 3-pointers shy of passing Dirk Nowitzki (1,705) for 15th place on the NBA's career 3-pointers list. ... Cleveland SF Richard Jefferson's next basket will be the 5,000th of his career. ... Hornets G Jeremy Lamb could return to the lineup Friday when the Hornets host Atlanta. Lamb missed the last six games with a strained left hamstring. ... Charlotte C Roy Hibbert is battling soreness in his right knee and is expected to have his minutes limited for the next few games. He played 13 on Sunday.
