BIG PICTURE

East Carolina: The Pirates led 3-2 following Fleming's 3-pointer with 17:23 remaining in the first, but Houston dominated the rest of the game. The Pirates struggled from the field but also struggled defensively to put pressure on the Cougars, who had a lot of open shots in the first half.

Houston: After its loss at Memphis, Houston rebounded in a big way. The Cougars played well defensively, which led to 12 turnovers and 19 points off turnover. Houston outrebounded the Pirates 46-17 and had 31 assists. Gabe Grant came off the bench to score 12 points.

TIMEOUTS

East Carolina interim coach Michael Perry used three of his four timeouts in a span of 2 minutes, 43 seconds in the first half while the Cougars were going on their run. Perry called his first timeout with 14:56 left in the opening half and called his final of three timeouts with 12:13 remaining.

HOME SWEET (TEMPORARY) HOME

The Cougars improved to 14-0 at home this season. Houston is playing this season at Texas Southern's H&PE Arena while construction continues on Houston's on-campus Fertita Center.
