The right-hander struck out six Ducks (7-2) while allowing only four hits in his first collegiate complete game.
Oregon got on the board first with a run in the fourth inning on a Ryon Healy RBI double, but Fullerton (9-0) answered back when Anthony Hutting singled home a run in the bottom half of the frame.
Fullerton took a 4-1 lead in the fifth inning. After Chad Wallach led off with a single, the Titans scored three runs without the benefit of a hit, taking advantage of two walks, two wild pitches and a passed ball.
The Titans tacked on four unearned runs in the next inning thanks to a two-out grounder that went through second baseman Aaron Payne’s legs. That was more than Eshelman needed as he finished off the 95-pitch complete game retiring nine of the final ten batters he faced.
