O.J. Mayo scored 20 points to lead six Dallas players in double figures and the Mavericks, despite the absence of Dirk Nowitzki, added to their mastery of Phoenix with a 109-99 victory over the Suns on Friday night.
Darren Collison added 19 points and Vince Carter 17 for the Mavericks, minus Nowitzki for the second game in as many nights because of a sore right hip.
Shannon Brown scored 20 and Goran Dragic added 19 points, nine assists and eight rebounds for the Suns, 0-3 against Dallas this season and losers of 11 of the last 12 in the series.
The Suns lost at home for the first time in four games since interim coach Lindsey Hunter took over from the fired Alvin Gentry.
