The AP reports: Maybe it was facing buddy Steve Nash. Maybe it was having two point guards in the starting lineup. Maybe it was the way Phoenix kept switching defenders against him without ever finding a stopper. Something put Dirk Nowitzki into quite the scoring mood. Nowitzki scored 37 points in three quarters and wound up tying his season high of 39, and the Dallas Mavericks continued their recent surge with perhaps their best performance of the season in a 112-97 victory over the Phoenix Suns on Thursday night… “We haven’t found a rhythm or a good balance yet,” said Nash, who had 20 points and 10 assists without playing the fourth quarter… Amare Stoudemire led Phoenix with 28 points but got his fifth foul late in the third quarter and wasn’t a factor after that… Barea, who earned the start by hitting the winning shot in the final minute of the previous game, finished with a season-best 18 points. Terry scored 19, continuing his strong play off the bench to make up for the scoring punch lost by Josh Howard being out with an ankle injury. Dallas is 6-1 in the seven straight games he’s missed.
