That's when Smith took over.
The Boonsboro junior made the lane his proving ground, slicing through for layups and positioning himself for rebounds. He had 13 points and eight rebounds in the second quarter (24 and 14 for the game).
He sparked a 9-0 run late in the frame as the Warriors went into halftime only down 41-38, and was the main reason the Warriors held a 21-10 rebounding edge at half.
"We got to an 11-point lead, and Lonnell decided he was gonna take over," Leopards coach Eric Gerber said.
But even though Boonsboro (12-10) closed the gap, the Warriors never got the tying or go-ahead points.
The Warriors hurt themselves with three blown layups and two turnovers early in the third quarter - when Smithsburg's offense was also sputtering.
"They only scored one point (in those possessions)," Ingram said. "We could have gone from down three to up four or five."
When Boonsboro did score (cutting the lead to two seven times in the third quarter and to one once early in the fourth), Smithsburg answered every single time to keep control.
Then, with Smithsburg leading 58-55, Smith picked up his fifth foul with 6:05 remaining. The Leopards extended the lead to 64-55 with 4:52 left.
Boonsboro surprised Smithsburg with a full-court press and forced eight turnovers the rest of the way, cutting the lead to 66-61 with 2:45 left.
But Ryan Marquiss (15 points, seven assists, five rebounds, three steals) found Corey Brown twice in transition for easy layups down the stretch, and Borwn's exclamation, one-handed tomahawk dunk on a breakaway put away the Warriors.
"From halfcourt, I was like, 'oh man.'" Brown said. "I had my eye on the rim."
"In transition, Corey is our money guy down under the basket," Marquiss said.
Keith Kellinger had 21 points - 10 in the first quarter and six in the fourth - for Boonsboro, which made just 16 of 29 free throws. Smith's only flaw was a 6-for-13 effort at the line.
"What killed us all year is our foul shooting," Ingram said. "When you look at the stats, that's it. It's been our Achille's Heel all year."
