The Nittany Lions drove 40 yards to the Ohio State 39 on their first drive before punting then went 63 yards for a field goal on their second drive.

PSU quarterback Trace McSorley was 6 for 7 for 89 yards passing and ran five times for 67 yards (including a sack that lost two) in the first quarter, but Ohio State kept him and the rest of the Nittany Lions bottled up for most of the second quarter.
One slip-up proved costly, though, as McSorley hit KJ Hambler over the middle and watched him outrun the Buckeye defense for a 93-yard touchdown that electrified a “White Out” crowd.
The second scoring play of that length Ohio State has yielded this season put the fourth-ranked Buckeyes in a 13-0 hole that looked even larger given their struggles on offense to that point.
