Loyola boys lacrosse head coach Jack Crawford knew that the No. 6 Dons needed to control the tempo by limiting possessions to beat visiting No. 1 Boys' Latin.
And Loyola did just that as it upset the top-ranked Lakers, 7-6, on Saturday.
"You can't let Boys' Latin have a lot of possessions, because they will score," Crawford said. "Loyola managed to win the ground-ball battle."
Boys' Latin (10-2) took a 1-0 lead before the Dons (10-3) scored two straight goals in the first quarter.
Loyola outscored the Lakers in three of the four quarters, including a 3-0 run in the third.
Andrew Dempsey brought Boys' Latin to within one with 25 seconds left in the game, but on the next possession Loyola defenseman Emmett Cahill stripped the ball with four seconds left to preserve the win.
Adam Smith scored twice for Loyola. Wells Stanwick, the Johns Hopkins-bound junior, led the Lakers with three goals.
No. 9 Fallston 12, Mercy 11: Freshman Aubrey Wettzelberger had a game-high four goals in a losing effort for the visiting Magic (1-12).
After playing to a 7-7 halftime draw, the Cougars (7-1) opened a four-goal lead early in the second half.
The Magic (1-12) answered with a 3-0 run over a 1:40 span. Fallston held off Mercy over the final 5:30 to preserve the win.
Jenna Mosketti, Jen Ward and Abby Wilson all had hat tricks for the Cougars.
St. Paul's 12, No. 13 C. Milton Wright 8: The host Gators went on two 5-0 runs to control the tempo as they upset the Mustangs (9-2).
Kelsey Boyd had a game-high five goals for St. Paul's.
C. Milton Wright closed the scoring gap to 6-5 before the Gators went on their final 5-0 run.
