CLEVELAND — Still unbeaten, still undeniable.

The Cavaliers are rolling through the East with ease.

LeBron James hardly missed and scored 24 points in three quarters, Kyrie Irving scored 27 and Cleveland picked up where it left off before a long layoff by thumping the Toronto Raptors 115-84 in Game 1 of the Eastern Conference finals on Tuesday night.

James made his first nine shots — one an arena-rattling powerhouse dunk — and the Cavs, healthy and hungry after losing in the Finals a year ago, shot 67 percent from the field in the first half while improving to 9-0 this postseason. Cleveland is the first team to start the playoffs with nine straight wins since San Antonio reeled off 10 in a row in 2012.

“It’s our preparation,” James said.
