LOS ANGELES, United States (AFP) — The Cleveland Cavaliers overcame a bout of fourth-quarter jitters to take a grip of their NBA play-off series against the Indiana Pacers on Monday night as San Antonio seized control of their duel with Memphis.

Cleveland appeared to be coasting to victory after opening up an 18-point lead at the end of the third quarter at the Quicken Loans Arena.

But the Cavs put the home fans through the ringer in a nervy finale as the Pacers punished a litany of mistakes to cut the gap to four points with 18 seconds remaining.

It mirrored a similar shaky finish in Game 1 when Indiana wiped out a 10-point fourth-quarter lead before Cleveland ground out a win. They also blew a 26-point fourth-quarter lead in a defeat to Atlanta earlier this month.

But the NBA Champions just about held their nerve on Monday, eventually winning 117-111 thanks to a 37-point haul from Kyrie Irving, as well as 27 points from Kevin Love and 25 from LeBron James.

James was unfazed by the Pacers’ fourth-quarter fightback after the Cavs held on to take a 2-0 lead in the best-of-seven series. Game 3 takes place in Memphis on Thursday.

“We’re right there,” said James, who also had 10 rebounds and seven assists. “We’re right there of what we know we can become, and we’ll figure it out.”

Cavs Coach Tyronn Lue blamed fatigue for the high turnover count that allowed San Antonio to claw their way back into the contest in the fourth quarter.

“I just saw turnovers,” Lue said. “We’ve gotta take care of the basketball. We turned the ball over and it hurt us. Nineteen turnovers for 24 points. It’s hard to win play-off games like that.”

The victory came at a cost for Cleveland, however, with guard J R Smith limping off with a hamstring injury. However, Smith’s replacement, Iman Shumpert, impressed from the bench with five points.

“We have so many pieces on this team, but everyone has to stay ready,” Irving said of Shumpert’s cameo.

“He had that mindset, came in and executed, and it’s hard to come off the bench right after half-time. We just need Shump to stay focused and understand the task at hand, and I think he did a good job of that tonight.”

In San Antonio, Memphis Coach David Fizdale was left fuming after watching his team slide to a 96-82 loss against the Spurs in their Western Conference showdown.

Kawhi Leonard finished with 37 points as the Spurs took a 2-0 lead in the best-of-seven series at AT&T Center.

But Fizdale unleashed a spectacular post-game tirade against the officiating crew, which is almost certain to bring disciplinary action from the league.

Fizdale complained bitterly that officials had unfairly skewed the free throw count against his players.

The series now moves to Memphis for Game 3 on Thursday.
