IOWA CITY, Iowa (AP) – Kamille Wahlin scored all 13 of her points in the second half and Iowa upset No. 13 Purdue 59-42 on Saturday, snapping the Boilermakers’ 11-game winning streak.  Center Morgan Johnson added 17 points and 11 rebounds for the Hawkeyes (12-10, 4-5 Big Ten), who had lost four of their last five games. Purdue’s Brittany Rayburn hit a 3-pointer to cut Iowa’s lead to 40-37 with 11 minutes left, but the Hawkeyes answered with a 16-2 run over an 8-minute stretch to pull away.  It’s the first Big Ten loss for Purdue (18-4, 8-1), which was beaten for the first time this month.  This was a tough and sloppy game from the start. Iowa led just 23-21 at halftime. The teams combined for 43 fouls and 29 turnovers.  The Boilermakers had won 16 of the last 19 meetings with Iowa, including a 57-55 victory on Jan. 15 in Mackey Arena.
