LAS VEGAS (AP) — Braelon Allen ran for 159 yards and Wisconsin drained the final 9:57 off the clock with an 18-play drive that sealed a 20-13 victory over Arizona State in the Las Vegas Bowl. Allen, the 17-year-old true freshman from Fond Du Lac, Wisconsin, had 101 yards by halftime for his eighth 100-yard game of the season. Graham Mertz finished 11 of 15 for 137 yards and a touchdown to senior tight end Jake Ferguson, who caught three passes for 33 yards in his final game for Wisconsin. The Badgers started 1-3 with Big Ten losses to ranked opponents Penn State and Michigan but answered with a seven-game winning streak to earn a 20th consecutive bowl bid.
