Right-hander Mike Willis pitched five scoreless innings in relief and Max Costes drove in the winning run with a sacrifice fly in the fourth inning as host Gilman upset previously undefeated and No. 1 John Carroll, 3-2, in Maryland Interscholastic Athletic Association A Conference baseball play Monday.
Willis, who took to the mound at the start of the third inning with the game tied at 2, allowed one hit and retired the last seven batters. Gilman is 8-10 overall and 6-6 in the MIAA A, while the Patriots (16-1) fell to 11-1 in league play.
Costes finished with two hits and drove in two runs.
