Jacksonville (2-15, 0-6 A-Sun) turned the ball over 19 times, with ETSU converting them into 23 points. Evin Graham, Aloys Cabell and Keith McDougald all scored 10 points to lead the Dolphins.
“We made a lot of turnovers and ETSU is a team that makes you pay for your mistakes,” said JU head coach Cliff Warren. “Our guys are working hard to get better each day and that continues to be our focus.”
After a Cabell 3-pointer cut the deficit to 15-14 with 11:53 left in the first half, ETSU closed the first half on a 24-5 run – capping it by holding the Dolphins scoreless for the final three minutes en route to a 38-19 lead.
Jacksonville fell behind by as many as 22, but battled back to cut the deficit to 11, 63-52, thanks to an 13-3 run that was capped by a pair of Delwan Graham free throws with 2:56 left in the game.
With a chance to cut the lead to single digits, Chris Davis made a turnover and the Bucs scored six in a row to seal the victory.
The 10-point night was a career best for Evin Graham, who was perfect on all four field goal attempts. JU had one of its better shooting halves of the season, hitting 48 percent in the second half, but committed nine turnovers.
ETSU got 16 points and nine rebounds from Tommy Hubbard, 13 from Isiah Brown and 11 from Sheldon Cooley.
Delwan Graham led JU with eight rebounds off the bench.
