MIAMI (AP) — Dwyane Wade scored 38 points, James Jones set a Miami postseason record with 25 points off the bench, and the Heat struck first in their Eastern Conference semifinal series by beating the Boston Celtics 99-90 on Sunday.

LeBron James finished with 22 points, six rebounds and five assists for Miami.

Ray Allen scored 25 for Boston, which lost for the first time in five games this postseason.

Paul Pierce scored 19 points before being ejected in the fourth quarter after picking up two technical fouls in a 59-second span.

Delonte West finished with 10 for the Celtics, while Rajon Rondo and Kevin Garnett were held to a combined 14 points on 6-for-19 shooting.

It was physical throughout, with West earning a technical and Jermaine O’Neal picking up a flagrant foul along the way, before things really got hot in the fourth. Pierce took offense with a hard foul by Jones, each getting double-technicals there, and Pierce and Wade — who have a bit of history — renewed acquaintances not long after that.

Grizzlies 114, Thunder 101

OKLAHOMA CITY (AP) — Zach Randolph had 34 points and 10 rebounds, Marc Gasol added 20 points and 13 boards, and the Memphis Grizzlies overpowered the Oklahoma City Thunder inside for a 114-101 victory in the opening game of the Western Conference semifinals on Sunday.

Just as they did in a surprising first-round upset of top-seeded San Antonio, Randolph and Gasol provided enough punch to give eighth-seeded Memphis a road victory in Game 1.

Randolph and Gasol each scored 20 points in the same regular-season game only once this season, but did it in Game 1 against the Spurs and again to negate the Thunder’s home-court advantage right from the start.

Kevin Durant led the Thunder with 33 points and 11 rebounds. Russell Westbrook scored 29.
