That puts behind him only behind only Todd Blackledge, Chuck Fusina and Tony Sacca - each at 29 wins - on the all-time list in the 132-year history of Penn State football.
Many expected the game to be a shootout, with lots of points scored, with Penn State ultimately finding a way to pull it out in the second half.
McSorley has 35 starts of the Nittany Lions, with four regular season games (at MI on Saturday, followed by Wisconsin, Rutgers and Maryland) and a bowl game remaining.
Penn State now enters perhaps their toughest three game stretch of the season with home games against Iowa and Wisconsin sandwiched around a showdown at MI.
Realistically, the Iowa defense allowed two big plays: Penn State quarterback Trace McSorley's 51-yard touchdown run and his pass to receiver K.J. Hamler for 39 yards.
Update: McSorley returned a couple of series later with a limp.

"I guess that's something that if there's any sort of secret out there, I guess that would be it - just investing in your body outside of practice and outside of everything that you're doing on the field". "I do not care what anyone says because he is as tough as it gets".

"I wasn't really going to know until I got out there", said McSorley, who finished with 167 yards passing and 63 rushing. In the first quarter.
Scott jumped up and made the interception.
Then, after Iowa quarterback Nate Stanley threw his second interception of the game, one that at the time appeared to hammer the final nail into the Hawkeye coffin, the defense forced a Nittany Lion three-and-out, giving the offense one final shot. They last lost three straight at home in 2015. The offense showed glimpses of their earlier-season self as they took the ball the length of the field few times and showed a more functional use of the LION package than against Ohio State. Penn State has played four straight games decided by six points or fewer for the first time since 1894.
