MEMPHIS, Tenn. --- Chris Douglas-Roberts scored with 2:31 left to break a 60-all tie, and top-ranked Memphis remained the country's only undefeated team Saturday by pulling out a 70-64 victory over Texas-El Paso.
The Tigers (21-0, 7-0 Conference USA) are enjoying their best start ever, topping the 20-win start by the 1985-86 squad. They also extended the nation's longest home-court winning streak to 44 in the first of a four-game homestand.
This was the tightest game of the season for a team that had been winning league games by an average of 25.7 points.
Credit goes to UTEP coach Tony Barbee and his Miners (13-7, 4-3), who constantly switched defenses and flustered the Tigers. Barbee knows Tigers coach John Calipari well from working as his assistant at Memphis between 2000 and 2006.
