O.J. Mayo had Denver beat with a tie-breaking 3-pointer late in regulation. The mistake-prone Dallas guard gave the Nuggets another chance to set a franchise record in wins with a turnover in the final seconds, so he had to hit another go-ahead shot from long range in overtime. Dirk Nowitzki scored 22, Mayo overcame his huge mistake with his first 20-point game in more than a month and the Mavericks denied the Nuggets their 55th win with a 108-105 overtime victory on Friday night.
