WASHINGTON -- Georgetown jumped out to an 8-2 halftime lead then withstood a second half rally from No. T9 Marquette to hold on for a 10-9 victory at Multi-Sport Field on Saturday afternoon.

Midfielder Craig Berge scored the eventual game winner on an extra-man opportunity, breaking a 9-9 tie with 3:45 left in the game. Marquette would have one final opportunity, but a shot hit the post with 10 seconds remaining and midfielder William Flatley picked up the ground ball as time ran out on the Hoyas' 10-9 win.

Georgetown notched its second victory against a Top-20 opponent this week, handing the Golden Eagles, previously one of three undefeated teams in NCAA Division I, their first loss of the season. Midfielder Anthony Heaton stepped in at the faceoff-X and went 13 of 23 with six ground balls, including a perfect 7-for-7 in the first quarter.

Attack Bo Stafford led GU with two goals, while eight other Hoyas scored one goal apiece in a balanced offensive effort. Defender Michael Mayer had five ground balls and caused two turnovers to help hold Marquette to nine goals.

The Hoyas started quickly as attack Stephen Quinzi found attack Reilly O'Connor for the first goal of the game at the 12:59 mark in the first quarter. Stafford scored an unassisted goal just over a minute later, before Marquette's Kyle Whitlow answered.

Midfielder Ryan Hursey and midfielder Eduardo White each scored to give GU a 4-1 lead late in the first quarter.

After a Marquette goal, the Hoyas exploded for four consecutive goals in the second quarter as Stafford, midfielder Charlie McCormick and midfielder Corey Parke each scored. Midfielder Nick Carpenter scored his first collegiate goal with 4:03 left in the half to put GU in front 8-2.

The Golden Eagles responded in the third quarter, using a 4-1 run to close within three goals at 9-6. Quinzi's unassisted goal at the 5:57 mark was the lone Hoya goal in the third quarter.

Marquette scored the first three goals of the fourth quarter to tie the game with 6:07 on the clock. A pair of unsportsmanlike conduct penalties on the Golden Eagles gave GU a man-up opportunity that they would capitalize on, as Berge scored at the 3:45 mark for the eventual game-winning goal.

Freshman goalie Nick Marrocco made seven saves and picked up six ground balls for his sixth collegiate win.
