The senior right-hander provided another "warrior-like" performance Friday when he pitched the Buccaneers to a 1-0 victory over No. 21-ranked Mercer in an Atlantic Sun Conference clash at Claude Smith Field.
Doane (11-1) tossed his fourth complete-game shutout this season and limited the powerful Bears (37-14, 15-7) to five hits. He struck out five and walked none.
In recording his NCAA-best 10th complete game of the year, Doane moved one win away from tying the ETSU single-season record for victories.
The Bucs (29-20, 14-8) plated the only run of the night in the seventh inning when Mason Hershey's sacrifice fly to right scored pinch-runner Zach Thompson. From there, Doane retired nine of the final 10 Bears batters he faced.
ETSU, which has won seven of its past nine games, moved back into a tie for third place in the A-Sun standings after Florida Gulf Coast lost to North Florida 8-7 in 11 innings.
The Bears' Brandon Barker (6-1) suffered his first loss of the season despite allowing just one unearned run on four hits in eight innings of work.
Game 2 of the series is Saturday night. First pitch is set for 7 p.m.
