ETSU hangs on in 71-70 win over Mercer
Trailing by two at the break, ETSU opened the second half with a 14-2 run fueled by four straight 3-pointers to take a 48-38 lead that it would hold the rest of the way. Riley hit the go-ahead 3 with 16:24 to go, sank another from long range and capped the burst with a pair of free throws.
Mercer (8-9, 3-1) held the Buccaneers scoreless over the final 3:25 and pulled within a point on an 8-0 run sparked by Jordan Strawberry's jumper.
Jestin Lews led the Bears with 17 points.
