The Tigers (11-8, 3-4 Atlantic Coast Conference) had let a double-digit lead slip away and trailed 59-58 when Jennings took over. His foul shot with 3:20 remaining gave Clemson the lead for good at 61-60. Damarcus Harrison's 3-pointer extended the lead and Jennings inched the ball over the rim moments later, then added two more foul shots for a 68-62 lead. The Hokies never got closer than four points the rest of the way.
Jennings, a senior, also tied his career best with 14 rebounds and provided the push for Clemson when leading scorer Devin Booker was held without a field goal and just three points.
Erick Green, the ACC's leading scorer, had 25 points for Virginia Tech (11-8, 3-3).
