RUSKIN — Lennard had Riverview on the ropes for much of the night Friday. But the Longhorns couldn't quite seem to dial in the range for the knockout punch.Enter Jalen Harrison.The sophomore defensive back returned a fumble for a late TD and the Longhorns shook off two games worth of penalties to remain perfect, beating back visiting Riverview 34-17."I just kept telling myself, 'Keep running, keep running,' " Harrison said. "Just keep going."With just under 10 minutes to play, Riverview's Matt Cochran connected on a 33-yard field goal to cut Lennard's (3-0) lead to 27-17. The Sharks then recovered the mishandled pooch kick, regaining possession and momentum.Riverview (2-2) got down to the Lennard 22, but Harrison hit Tamel McCall to jar the ball loose. Harrison scooped up the loose ball and outraced everyone down the left sideline for a 79-yard TD with 6:56 remaining to seal it."I came over, made a big hit and picked it up," Harrison said. "From there I just took it to the crib."Lennard was far from sharp. The Longhorns were whistled for 16 penalties, their receivers combined for five drops and the defense whiffed on a number of second-half tackles."We left about 28 points on the board in that first half," Lennard coach Keith Chattin said. "And way too many penalties. We've got a lot to clean it up."Lennard tailback Jahryn Bailey found the end zone three times (12, 10 and three yards), finishing with 42 yards rushing on 10 carries. Devin Black (13-of-25 for 226 yards) hit Deshawn Barnes (five catches for 114 yards) for a 55-yard TD pass on the final play from scrimmage in the first half.Chattin, however, was not impressed with his offense."I think we were flat," Chattin said. "We didn't come out to play and that's two weeks in a row we played really bad on offense."Quon Lambert (team-high 82 yards rushing) scored from three yards out and Antonio Evans did the same from 10 for the Sharks' scores. Riverview's Kyle Peacock and Lennard's Ramon Bence finished with a pair of sacks apiece.
