The third scoring spree proved to be the charm for Lincoln-Way East.
The Griffins broke out to a quick 17-point lead, but the St. Anthony Bulldogs got back to within six.
LWE then built a 15-point cushion, only to see SAHS battled back to within four.
But a 15-0 run at the end of the first half and into the third quarter proved to be the knockout blow Wednesday afternoon, as the Griffins went on to post a 64-47 victory and earn a berth in the semifinals of the 8th annual Effingham-Teutopolis Christmas Classic.
