Navy 11, Lehigh 5: It would not be overstating things to call Wednesday night's game against the Mountain Hawks a must-win for the Mids.
Navy was seeking to avoid suffering a four-game losing streak and falling to 0-3 in the Patriot League for the first time in program history.
Sophomore attacker Julia Collins (River Hill) led the way with four goals as the Mids broke out of an offensive slump to secure a crucial conference victory over second place Lehigh, 11-5. Freshman midfielder Meg O'Donnell totaled two goals and an assist for Navy, which outscored the visitors 5-1 in the second half.
Senior attacker Katie Gallagher (C.Milton Wright) and sophomore midfielder Jenna Collins (River Hill) contributed two goals apiece for the Mids (6-4, 1-2), who have won seven straight against the Mountain Hawks (7-2, 2-1). With another loss, Navy was in danger of missing the Patriot League tournament for the first time.
"This was, without a doubt, the biggest game of the season so far," Julia Collins said. "We had to win this or there could have been a chance our season was kind of over based on not going to Patriot's. So it was very important."
