CLEVELAND, April 10 (Ticker) -- Paul Silas was right after all about Jeff McInnis.

McInnis scored 16 points and handed out eight assists as the Cleveland Cavaliers posted a 91-80 win over the playoff-bound Miami Heat.

Silas, the Cavaliers' first-year coach, has maintained that shoulder and ankle injuries to McInnis -- the point guard acquired from Portland during the season -- were behind his team losing 11 of its previous 12 games and falling out of the Eastern Conference playoff chase.

"Well, (McInnis) leads the charge, we all follow," Silas observed. "It's just an impossibility to play a system without his production, so it's just a whole different ballgame."

The Cavaliers (33-47) snapped a seven-game slide and need one win in their last two games to double last season's win total.

The Heat (40-40) missed an opportunity to tie Milwaukee for fourth place and possibly gain home-court advantage in the first round of the playoffs.

McInnis scored on a driving layup at the end of the first quarter to give Cleveland the lead for good at 22-21. That bucket jump-started an 11-0 run, and the Cavaliers were in command the rest of the way, leading by as many as 25 points in the fourth quarter.

"I keep telling you all, when our quarterback is playing we're a better team," Cavaliers rookie standout LeBron James said.

James, coming off 24 points, eight assists and seven rebounds in Friday's loss at Miami, finished with 10 points and 11 assists.

Tony Battie contributed 12 points and 10 rebounds off the bench. Center Zydrunas Ilgauskas added 11 points in just 22 minutes and Carlos Boozer added 10 points and 14 rebounds.

"If we get one of these two wins (and reach 34), that's a big success," James said.

The Heat, who are 18-8 since the All-Star break, have slim hopes of earning the home-court advantage after falling into a fifth-place tie with New Orleans. They need to win their final two games and hope fourth-place Milwaukee drops its final two.

"We haven't had one of those (blowout losses) in a long time," Heat coach Stan Van Gundy said. "We've probably had as long a stretch as anybody in the league without having one of those. So, I don't want to go overboard, but we've sort of been building toward that in terms of our defense."
