• Member of a Navy defensive that held Loyola scoreless for 22:58 between the 3rd (13:03) and 4th (5:05) quarters ... it allowed Navy to go on a 3-0 run and take the lead for good

• Navy’s defensive unit held #17 Colgate to just 2 goals over nearly a 30-minute stretch (8:06 1Qtr - 8:26 4Qtr), allowing Navy to overcome an early 4-0 deficit and eventual 10-9 win ...  the Mids held Colgate, who came into the game averaging 13.00 goals per game, to single digits (9) for just the 2nd time (Villanova) this season
• Navy’s defense held Boston U. scoreless for nearly 22 minutes between the 2nd (3:33) and 4th (11:44) quarters, while Navy went on a 5-0 run and built a 6-goal advantage (12-6) ... the Mids contained the high-powered offense that entered the game averaging 13.5 goals per game
