ERIE, Pa. -- Seniors Jamie Wesztergom and Christine Bradley scored overtime goals as East Stroudsburg survived a late comeback in regulation to earn a 15-14 upset victory at No. 10 Gannon in PSAC lacrosse on Tuesday afternoon in northwestern Pennsylvania.

Wesztergom had four goals and two assists for a career-high six points to lead the Warriors, who held a 13-9 lead with just over four minutes remaining before the Golden Knights (6-3-1, 3-2) scored four consecutive goals, including the game-tying goal with 13 seconds left.

Bradley regained the lead for the Warriors (5-4, 3-2) less than a half-minute into overtime and Wesztergom scored her fourth goal of the game to make the score 15-13 with 1:07 left in the first three-minute overtime session.

In the second overtime, ESU sophomore goalkeeper Katie Zollo made three of her eight saves before Gannon pulled within one on a goal by Sarah Grzybinski with 44 seconds remaining. The Golden Knights won the ensuing draw control and earned a free position shot with eight seconds remaining, but Caitlyn Fisher went too quickly on the restart to turn the ball over and ESU ran out the clock to secure the upset.

The Warriors will look to knock off a second consecutive Top 10 team when they host No. 8 Mercyhurst on Saturday at 1 p.m. at Whitenight Field.

ESU used a five-goal run in the first 10 minutes of the game to take a 5-2 lead, and led for all but 37 seconds of the final 53 minutes before Gannon’s furious run to tie the game at the end of regulation.

Wesztergom got off to a quick start with the Warriors’ first two goals and added an assist in the first half, had a goal and an assist in the second half to complete her first hat trick of the year and ultimately scored the game-winning goal in overtime. Wesztergom and senior Molly O’Hara also had a game-high seven draw controls as ESU won the draw control advantage, 18-15.

The Warriors got the bulk of their offense from Wesztergom, O’Hara, junior Laura Riegel and sophomore Ali Green, who combined for 12 goals and six assists. O’Hara and Green both had three goals and an assist and Riegel had two goals and two assists for a career-high four points.

O’Hara’s hat trick was her sixth of the season and 31st of her career for the Warriors’ second-leading goal scorer in school history, while Green netted the second hat trick of her career.

ESU was outshot 35-28 and committed five more turnovers, 22-17, but junior Amanda Simms and Zollo combined for 11 saves in goal and the Warriors limited Gannon to 1-for-5 on free position shots in the second half.

The Warriors led 7-4 with 10 minutes left in the first half before Gannon scored three consecutive goals, two by Mary Eshenour, the PSAC’s leading scorer, to tie the game at 7-7 with 30 seconds left.

Junior Kelsey Pfautz scored her first goal of the season with six seconds left in the half to send ESU into halftime with an 8-7 lead, and the Warriors scored the first three goals of the second half – two by O’Hara and one by Green – to go ahead 11-7 with 21 minutes left.

Caitlyn Fisher scored twice to pull Gannon within 11-9 with 11 minutes on the clock before the Warriors reestablished their four-goal lead on goals by Riegel and Wesztergom at the seven-minute mark.

The Golden Knights cut the deficit to 13-12 with 2:44 remaining, setting off an exciting end to regulation. Green won the draw control, but the Warriors turned the ball over with just under 2:00 left. Gannon didn’t get a shot off until the final 30 seconds and Jess Fugate scored the game-tying goal to send the game into overtime.
