Chelmsford gave Woburn all it could handle, but eventually the Lady Tanners had just enough to snag an overtime win on Sunday night.
Fifth-seeded Chelmsford came to town and, despite falling behind by double digits early, sent the game to an extra session. But No. 4 Woburn was not rattled, snagging a 58-56 win in the North Division 1 quarterfinal round.
The victory propels the locals into the semifinal, where they will take on Lynn English in a game scheduled for Thursday at 7 p.m. in Danvers.
Whichever of those two teams moves on will head to play at the Tsongas Center in Lowell. The winner of the North Division 1 tournament will advance to the state semifinal.
