Unbeaten Ohio State was unblemished Saturday.
Doran Grant picked off Danny Etling's first pass, returning it for a touchdown, and Braxton Miller threw for 233 yards and four touchdowns to lead the fourth-ranked Buckeyes to a record-breaking 56-0 victory at Purdue.
Ohio State (9-0, 5-0 Big Ten) kept its national title hopes alive by extending the nation's longest winning streak to 21 in a row - and they did it in a venue where they had lost three of their last four.
Coach Urban Meyer, who hasn't lost in 34 1/2 months, tied his personal best by winning a 22nd straight game, a streak that includes his final victory at Florida. Meyer also won 22 in a row with the Gators in 2008-09.
Ohio State won this one in dominant fashion, too, scoring the most points and producing the most lopsided victory in the history of this 56-game series. Both of the previous marks came in 2010 when Ohio State beat Purdue 49-0. Miller was 19 of 23 despite not playing in the second half.
