The Cleveland Cavaliers withstood a late surge from the Indiana Pacers to win the opening game of their Eastern Conference playoff series, while Kawhi Leonard inspired the San Antonio Spurs.
Defending NBA champions the Cavaliers emerged triumphant in game one of the first round, topping the Pacers 109-108 on Saturday.

The Milwaukee Bucks snapped an unwanted losing streak in the playoffs with a 97-83 victory over the Toronto Raptors, while the Los Angeles Clippers fell 97-95 to the Utah Jazz.
CAVS PUT REGULAR-SEASON WOES BEHIND THEM
The Cavs had lost their final four games of the regular season in an alarming form slump.
But the titleholders - seeded second in the east - sent a timely reminder to their rivals, albeit in nervy fashion.
James added 13 assists and six rebounds in his 200th playoff game as he won his 18th consecutive first-round match.
Kyrie Irving added 23 points for the Cavaliers, who won their 12th successive playoff game on home court.

Game two is on Monday.
SPURS MAKE IT LOOK EASY

Despite being outscored 30-25 in the first squad, the Spurs surged to blitz the visiting Grizzlies.
LaMarcus Aldridge scored 20 points and Tony Parker contributed 18 of his own with game two back in San Antonio on Monday.
Marc Gasol had 32 points for the Grizzlies, who trailed by as many as 36 against the Spurs.
BUCKS END LONG PLAYOFF STREAK
Led by Giannis Antetokounmpo, Milwaukee pulled away from the Raptors in the second half in Toronto.

Antetokounmpo, who had a game-high 28 points, had an emphatic block of DeMar DeRozan with less than two minutes remaining and the Bucks comfortably holding a 95-76 lead.
TRY AND STOP KAWHI
JAZZ LOSE GOBERT BUT WIN
Centre Rudy Gobert left the opening-round playoff game after just 13 seconds.
While setting a screen, Gobert knocked knees with Clippers forward Luc Mbah a Moute and fell to the court at Staples Center.
Gobert, who averaged 14 points, 12.8 rebounds and 2.6 blocks this season, had to be helped off the court but the Jazz still won thanks to Joe Johnson's 21 points. Gordon Hayward had 19 points and 10 rebounds.
WARRIORS AND CELTICS IN ACTION
