NEW YORK (REUTERS) - After establishing an early double-digit lead on Thursday, the Miami Heat never relinquished the advantage.

Dwyane Wade scored 27 points to lead the Heat to a 108-92 victory over the Phoenix Suns in the National Basketball Association league.

Goran Dragic finished with 25 points and Luol Deng scored 12 points for the Heat, who improved to 6-2 since the All-Star break.

"We're playing unselfish basketball," Wade said. "Any given night, anybody can be more aggressive than other guys, depending on match-ups, depending on the night."

Rookie Devin Booker scored a career-high 34 points, including 15 in the fourth quarter, for the Suns, who have lost 15 of 16 games overall and 17 straight on the road.

The road losing streak matches Phoenix's all-time record, set from Jan 4-March 13, 1974.

The Heat (35-26) were never threatened after extending a four-point lead late in the first quarter with a 20-5 run that ended midway through the second period.

Wade's jumper with 6min and 52sec remaining in the second capped the surge and increased Miami's lead to 45-26.

"What I liked about tonight is we came out early and took care of business," Wade said. "That's the NBA - a team is going to make runs. We did a good job of keeping them off."
