Whitestar, who have won just one league game so far this season, drew 3-3 with the current Premier Division leaders before holding their nerve to win 4-3 on spot-kicks at Sandylands.
Whitestar keeper Andrew Shutt saved several one-on-one chances and then two penalties.

Jamie Cunningham hit a screamer for Silsden on the hour-mark but Howson popped up again to take the tie into extra time.
Skipton continued to batter Whitestar’s goal, but Shutt was colossal. Oliver Hurst finally put LMS in front before Cox took the game into penalties with the last kick of the game and Whitestar held their nerve.
