The tie dropped the Spartans (3-0-1 Big Ten, 6-2-1 overall) out of first place in the Big Ten standings but preserved a 5-meet winning streak. Wisconsin (0-3-1, 7-3-2) snapped a 3-match losing streak.
The Badgers led 16-10 with two matches to go Sunday, but the Spartans Jeff Clemens beat Wisconsin's Ryan Flaherty at 197 and MSU's Max Lossen took a decision from Lee Kraemer at heavyweight to tie the score.
"I give credit to Michigan State because they came out to wrestle," UW coach Barry Davis said. "Will I take a tie, yes, but we got to step up. Not all of our guys are stepping up at the one time and right now we need to do that."
Wisconsin trailed 4-0 after one match but Tom Clum won a major decision at 133 and Tyler Laudon took a decision at 141 to give the Badgers a 7-4 lead. Michigan State took decision wins at 149 and 174, while the Badgers won decisions at 157 and 165. Brady Reinke gave the Badgers the 16-10 edge with a decision win at 184.
