Kip Skibicki's two-out single in the bottom of the seventh scored courtesy runner Hunter van Brussel with the winning run.
Tower Hill (19-1, 11-1) had beaten Tatnall (16-4, 10-2) in their two previous conference games, including 4-1 on Thursday.
"We knew we lost a tough game," Tatnall coach T.J. Ostrishko said of Thursday's loss. "But you don't let them go undefeated on your field. You have to defend your home field, and that's what we preached being down 8-0."
Tower Hill led 9-3 through four innings before Tatnall scored four runs in fifth. Justin Perillo's two-run home run in the sixth tied it 9-9. Tower Hill went ahead 10-9 in top of the seventh on James Mraz's two-out home run.
In the bottom of the seventh, with two outs, Chris Jones singled and took second on an error. Corey Ryan singled home Jones to tie it at 10-10, with Ryan moving to second on the throw home. After an intentional walk to Perillo, Skibicki followed with his game-winning hit.
