Landsowne (2-1) rallied for eight runs in the sixth inning to help overcome a 10-run deficit and beat host Towson (0-3) on Thursday, 14-13.
The Vikings trailed 11-1 in the top of the fifth inning and was two outs away from the game being called because of the 10-run mercy rule.
But Landsowne scored four runs in the fifth, highlighted by senior right fielder Cameron McCarthy's two-run homer.
The Vikings pushed across eight more runs in the sixth to take the lead for good.
Junior third baseman Nick Vucci had a home run, a double and two RBIs for the Generals.

Northeast 18, Annapolis 17: The only thing Northeast's Nikki Hallikas didn't do in Thursday's girls lacrosse game against Annapolis was make the game-clinching save. She left that to her team's freshman goaltender.
Hallikas scored five goals and won 15 draw controls to put the Eagles into a position to win. Goalie Sydney Wingate preserved the victory when she stopped a free position in the final seconds of Northeast's 18-17 victory over Annapolis at the South River Showcase.
The win is the first in school history for the Eagles over the Panthers. Annapolis' dominance in the series covered nearly 30 games.
With Northeast leading by a goal late, the Panthers had possession for the final minute of the game. Cammie Schniedwind was awarded a free-position opportunity with 3.8 seconds remaining, but Wingate made the stop for the biggest of her 15 saves.
