MIAMI --- Dwyane Wade knew his regular-season numbers against Boston were lacking.
He also knew that wouldn't matter in the playoffs.
And Game 1 -- which seemed more like Round 1 -- of what's already an emotionally charged series went to Wade and the Miami Heat.
Wade scored 38 points on 14 of 21 shooting, James Jones set a Miami postseason record with 25 points off the bench, and the Heat beat the Celtics 99-90 on Sunday to open their Eastern Conference semifinal series.
"We're going to have to fight for every inch, every game we get," Wade said. "Right now, we won Game 1. We're supposed to. We'll go back and focus on winning Game 2. We're at home, we have home-court advantage. They're just trying to come in and steal one like they've done in the past. So it's our job to come out with the same mentality in the next one."
LeBron James finished with 22 points, six rebounds and five assists for Miami, which led by as many as 19. Paul Pierce was ejected with seven minutes left after picking up two technical fouls in skirmishes with Wade and Jones within a span of 59 seconds. Ray Allen scored 25 points for Boston. Pierce scored 19 for the Celtics, while Rajon Rondo and Kevin Garnett were held to a combined 14 points on 6 for 19 shooting.
GRIZZLIES 114, THUNDER 101
In Oklahoma City, Zach Randolph had 34 points and 10 rebounds, Marc Gasol added 20 points and 13 boards, and Memphis overpowered Oklahoma City inside to take Game 1 of the Western Conference semifinals.
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 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.
