STATE COLLEGE (AP) -- Iowa extended its unbeaten streak to 73 dual meets by upsetting top-ranked Penn State 22-13 on Sunday.

The Hawkeyes, ranked No. 8 in the coaches' poll, won six of 10 bouts, including the first three.

Matt McDonough, the defending NCAA champion at 125 pounds, scored a fall to spark Iowa's 12-0 lead after three bouts.

The Hawkeyes then won at 165, scored an upset by No. 16 Grant Gambrall over No. 6 Quentin Wright at 184 and added a major decision at 197 pounds to secure the win.

Penn State coach Cael Sanderson, a former four-time NCAA champion and coach of Iowa State, again was denied a win over nemesis Tom Brands of Iowa.

The Hawkeyes (11-0-1 and 3-0 Big Ten) are now the only undefeated major program in the nation.
