Jayden Fielding’s third field goal put the Buckeyes (3-0) up 16-9 before Sayin found Smith for a 47-yard touchdown and Carnell Tate for a 49-yard score to make it a three-score game.
Smith, who had a career-high nine receptions for 153 yards, put it out of reach by going around left end on a 17-yard reverse to make it 37-9 midway through the fourth quarter. The sophomore also became the fastest player in school history to reach 1,500 yards receiving, reaching the mark in his 19th game.
Sayin completed 25 of 32 passes. He had his second straight 300-yard game but also had two interceptions.
Bo Jackson had 109 rushing yards on nine carries and Tate had five receptions for 101 yards and a TD.
The Buckeyes had 572 yards of total offense, including four plays of at least 42 yards, and held the Bobcats to 181.
Navarro completed six of 13 passes for 94 yards. The senior suffered a wrist injury late in the first quarter and didn’t come back until after halftime.
Making things interesting
Hendricks’ 63-yard TD was the longest catch of his career. The junior caught the ball in stride at the Buckeyes 41, revered field, stiff armed an attempted tackle by Ohio State cornerback Lorenzo Styles Jr. at the 23 and then outraced other Buckeye defenders into the end zone. Ohio kicker Brack Peacock missed the extra point to keep Ohio State’s advantage at 13-9.
The takeaway
Ohio: The Bobcats beat West Virginia last week and came within three points of beating Rutgers in the opener. They made it a game for 31 minutes at the Horseshoe before running out of steam.
Ohio State: Coach Ryan Day won’t like the lapses and turnovers, but at least there are plenty of things he can point out on tape that can be corrected before the Buckeyes begin Big 10 play in two weeks.
Up next
Ohio: Hosts Gardner-Webb next Saturday.
Ohio State: Has a bye week before a game at Washington on Sept. 27.
