UMBC won its second straight and improved to 4-5 on the campaign, while the Leopards dropped to 1-8.
A bevy of Retrievers posted career-best performances on the evening. Junior midfielder Pat Young (Ewing, N.J.) led all goal scorers with five and became the 32nd player in school history to reach the 100-point plateau. Senior attackman Conor Finch (Westminster, Md./Boys Latin) recorded career best in assists (4) and total points (6) and junior middie Jack Gannon (Lake Ronkonkoma, N.Y.) scored a career-best four times, all in the pivotal third quarter.
In his third career start in goal, sophomore Ruston Souder (Pasadena, Md./Chesapeake) made 17 saves, the most by a Retriever this season.
UMBC led, 5-2, at halftime, but bolted from the gate in the third quarter, scoring five times in the first 6:06 of the stanza. After a scoreless first half, Gannon accounted for three of those goals and all three were unassisted. Lafayette snapped the 7-0 run, which extended back to the second quarter on a goal by Sonny Round at the 7:20 mark, but Gannon tallied his fourth of the period just 65 seconds late and UMBC freshman Steven Partlow (Pasadena, Md./De Matha) capped the seven-goal period by netting his first career goal with nine seconds to play in the stanza.
The Retrievers led, 12-3, after 45 minutes and got three goals from Young and two from Finch in the fourth quarter as they added six in the final frame to amass their highest goal total since scoring 19 versus Vermont in 2013.
Sophomore attackman Eric Joseph was the lone multiple goal-scorer for the visitors with a pair.
UMBC never trailed, leading 3-1 after the first quarter as a Young shot from outside the box found the net with 1.8 seconds before the horn. Lafayette's Robert Orazietti brought his side to within 3-2 with 5:54 to play in the second quarter, but Young and sophomore attackman Max Maxwell (Hamburg, N.Y.) scored in a 42-second span to give the Retrievers the 5-2 halftime edge.
Souder made seven first half saves and stopped seven shots in the fourth quarter alone as Lafayette oushot UMBC, 43-39. Three Leopard netminders saw action, with starter Matt Cortese taking the loss, making five stops and allowing 11 scores in 38:25.
UMBC won 17 of 28 draws and freshman face-off specialist Brett Malamphy (Crofton, Md./Arundel) had his best effort to date, capturing 12 of 14 face-offs.
Young became just the eighth UMBC Division I player to score 100 points by his junior season. The last to accomplish that feat was Drew Westervelt, who hit the plateau in 2006. He now has 80 goals and 24 assists in 39 career contests. Young also had a five-goal game versus Hartford in 2014, but the six points (he added an assist) is a new career mark.
UMBC cashed in on 3-of-4 man-up opportunities in the game. After starting the season 1-of-13, the Retrievers have converted on 10 of their last 14 chances.
Maxwell added two goals and one assist for UMBC, while leading goal scorer Nate Lewnes (Arnold, Md./St. Mary's) (18 goals) posted his seventh career game of three goals or more with a hat trick.
UMBC returns to America East competition on Saturday, April 4 when they travel to Hartford.
