Amir Coffey spotted up in the right corner and launched a three-pointer as the seconds counted down in the first half Friday night.
After the ball sank through the net, the Williams Arena crowd came to life as their Gophers team took a nine-point lead into halftime against Southern Illinois.
Only a few minutes earlier, the Gophers had looked sluggish and appeared to be suffering from a Thanksgiving hangover. On top of that, they were playing without starting center Reggie Lynch, but they still managed to pull out a 57-45 victory over the Salukis.
"We needed a wake-up call there," Gophers coach Richard Pitino said. "We were not real connected. We were frustrated. That's attributed to missing shots. Fortunately we played defense."
Southern Illinois (3-3) shot just 31 percent, including 2-for-17 from beyond the arc.
The Gophers (6-0) saw their streak of five consecutive games with 80 points or more end on a night when they had their worst shooting performance of the season across the board. They were 38 percent from the field (21-for-55), 19 percent on three-pointers (3-for-16) and 55 percent from the foul line (12-for-22).
Coffey, who is averaging 20.7 points in his past three games, had a team-best 13 points Friday.
After injuring his ankle in the first half in Tuesday's victory over Arkansas, Lynch was a game-time decision against Southern Illinois. Freshman Eric Curry ended up replacing Lynch in the starting lineup, finishing with eight points and 11 rebounds. But he also had five turnovers.
