Iowa coach Kirk Ferentz also capped his 24th season by matching the late Joe Paterno for the most bowl victories among Big Ten coaches with his 10th.
Iowa (8-5) got a bit of payback for ending last season losing to Kentucky in the Citrus Bowl after a late comeback by the Wildcats. The Hawkeyes defense outscored its offense, returning two interceptions for TDs in the second quarter. The Hawkeyes finished the season with their fifth win in six games.
Kentucky (7-6) lost for the third time in four games, this time without quarterback Will Levis and running back Chris Rodriguez as both opted out to prepare for the NFL draft. The loss ended the Wildcats' school record streak of bowl wins at four straight.
The Hawkeyes scored all their points in the second quarter to seize control, scoring twice 11 seconds apart early in the quarter.
Taking his first snaps in a college game with Spencer Petras out with an upper-body injury, Labas hit Sam LaPorta with a short pass that the tight end took 27 yards pushing through defenders. Labas then found Luke Lachey for a short pass, and the tight end finished off a 15-yard touchdown with 12:08 left.
Drew Stevens pushed the ensuing kickoff out of bounds, setting Kentucky up at the 35. Freshman Destin Wade, also making his collegiate debut, was picked off by Iowa safety Xavier Nwankpa who went 52 yards for the 14-0 lead.
The Hawkeyes didn't miss All-American defensive back Kaevon Merriweather who opted out to prepare for the NFL draft. They posted their second shutout this season, holding Kentucky to 185 yards while sacking Wade four times and forcing the Wildcats to turn it over on downs twice.
Iowa must improve on offense, especially with the Hawkeyes losing All-American linebacker Jack Campbell. This was the Hawkeyes' sixth game this season posting 222 yards of total offense or less.
Kentucky: The Wildcats gave Wade, from nearby Spring Hill, some experience even with Devin Leary coming in the transfer portal to replace Levis. Wade finished with 98 yards passing and 29 yards rushing as Kentucky was shut out for the first time since Oct. 19, 2019, in a loss to Georgia.
