PISCATAWAY — John Blackwell scored 21, Steven Crowl totaled 18 points and 10 rebounds and Wisconsin defeated Rutgers 75-63 on Monday night. Blackwell made 8 of 15 shots with a 3-pointer and all four of his free throws as the Badgers (12-3, 2-2) upped their win streak to four. Crowl hit 8 of 11 shots with two 3-pointers on the way to his first double-double of the season. John Tonje added 15 points, nine rebounds and two blocks for Wisconsin. Tyson Acuff scored 17 off the bench to lead the Scarlet Knights (8-7, 1-3), who lost for the first time in seven home games. Blackwell had 13 points and Crowl scored 12 to help Wisconsin take a 43-34 into halftime. The Badgers scored the first six points and led by as many as 16 before the break. Rutgers closed within seven points before Kamari McGee hit a pullup jumper with one second left. Acuff scored 11 to pace the Scarlet Knights. Ace Bailey opened the second half with a 3-pointer for Rutgers to make it a two-possession game. The Scarlet Knights twice closed within three points — the second coming when Jeremiah Williams hit a pullup jumper to make 60-57 with 6:45 remaining. But Tonje answered with a 3-pointer and Blackwell scored four straight at the free-throw line to cap a 13-2 run, putting Wisconsin up 14 with 90 seconds left. Dylan Harper played just 15 minutes and sat most of the second half due to the illness that kept him out of Rutgers’ loss at Indiana on Thursday. The Badgers shot 54.4% from the floor and went 6 for 6 from the free-throw line. Rutgers shot 34.2% overall and made 6 of 13 at the foul line. Both teams hit seven 3-pointers. Rutgers will host No. 20 Purdue on Thursday. Wisconsin will host Minnesota on Friday.
