Miami ? They gave away a 17-point lead, turned the ball over 15 times, missed 11 free throws and received nothing resembling dominance from either Shaquille O’Neal or Dwyane Wade.

Didn’t matter. The Miami Heat still won with ease.

Wade overcame a poor start to score 20 points, O’Neal added 19 points in 26 foul-plagued minutes and the Heat defeated Washington, 105-86, Sunday in Game 1 of their Eastern Conference semifinal series.

“I think it was just being out of our rhythm,” Wade said. “We didn’t go for the jugular.”

The Heat’s depth was a key factor, with Miami’s reserves outscoring Washington’s 36-5.

Keyon Dooling had 15 points, Eddie Jones scored 12 and Damon Jones 10 for the Heat, who’ve won five straight playoff games for the first time in franchise history and are 5-0 against Washington.

“Everybody’s main focus is Dwyane and Shaq anyway,” said Dooling, who was 6-for-9 on his 25th birthday and is 20-for-26 in his last four games. “So there’s going to be shots and opportunities for everyone else.”

Deadpanned Wizards coach Eddie Jordan: “We gave them a run for their money, 36-5. We always have an ‘X’ factor. Today we had a ‘Z’ factor — zero.”

Gilbert Arenas had 25 points on 8-for-21 shooting for Washington. Larry Hughes added 23, Antawn Jamison had 13 before leaving in the fourth quarter with a sore right knee, and Jared Jeffries and Brendan Haywood added 10 apiece. Etan Thomas, with five points, was the only Washington reserve to score.

Spurs 103, SuperSonics 81

San Antonio — Not having to deal much with Ray Allen or Vladimir Radmanovic made things much easier for the Spurs.

San Antonio already had a double-digit lead when the Sonics lost both Allen and Radmanovic to right ankle sprains in the second quarter. After that, the Spurs’ lead reached 30 points before halftime in a victory in the opener of their second-round series.

Seattle coach Nate McMillan said X-rays were negative for both players, and they would be listed as day-to-day. Game 2 in the best-of-seven series is Tuesday night.

“I don’t want to even think about not having Ray Allen right now,” said Sonics center Jerome James, adding that if Allen couldn’t play, “I am more than ready to step up and play like I did in the last series.”

Neither Allen nor Radmanovic was around after the game.

The injuries occurred in a span of less than a minute early in the second quarter, and the Spurs took advantage by going on a 17-2 run that made it 58-28 with about two minutes remaining in the half.

Allen, an All-Star who averaged 32.4 points in the Sonics’ first-round-series victory over Sacramento, got hurt while driving to the basket.

Radmanovic rolled his ankle while defending Brent Barry and had to be carried from the court by teammates.

Rashard Lewis, who led the Sonics with 19 points, said the team had to step up its defense — with or without Allen in the lineup.

“We are playing a championship team, so we have to get it done on the defensive end,” Lewis said.
