Klesmit, who is from Neenah, Wisconsin, scored 14.9 points per game for Wofford this past season and earned third-team all-Southern Conference honors. The 6-foot-3 Klesmit also had 2.8 rebounds, 1.9 assists and 1.6 steals per game.
He had 8.2 points and 2.7 rebounds per game as a freshman in 2020-21.
This announcement comes three weeks after Wisconsin added Green Bay transfer Kamari McGee, a 6-foot guard from Racine who averaged 11.6 points for the Phoenix this past season.
Wisconsin must replace All-America guard Johnny Davis and second-leading scorer Brad Davison from a team that went 25-8, won a share of the Big Ten regular-season title and reached the NCAA tournament's round of 32 during the 2021-22 campaign.
