No. 12 Catonsville 1, Sparrows Point 0, OT: Luke Palmisano scored 13:27 into overtime to lift the host Comets (9-2-1) to a 1-0 victory over the Pointers (7-3).
The winning play started with a free kick from Liam Llorin from 60 yards out.
Matt Rehder headed it toward the goal and Ethan Clark flicked it to Palmisano.
"We missed a couple of good opportunities earlier in the game, so I called [Clark] off because I knew I had a better angle on it," Palmisano said.
"We just needed one solid shot on frame and that's what we got, and Luke buries that one," Catonsville coach Chris Hastings said.
The Comets had a chance to win 4:50 into overtime, but Llorin's penalty kick went wide.
Sparrows Point goalie Quentin Hager made 14 saves.
"They had a good goalie," Hastings said. "We just needed something hard and on goal."
That's when Palmisano delivered.
