Keeping his eyes on the ball paid off for Penn State's Bryant Johnson. The wide receiver made an acrobatic touchdown catch at the end of the first half to start run of three TDs in just 2:18 as the resurgent Nittany Lions beat Southern Mississippi 38-20 on Saturday. With four seconds left in the half, Zack Mills' pass to the end zone bounced high off the hands of the intended receiver, but Johnson caught the deflection just inside the end zone. ``The ball seemed to be in the air forever, and I just ran over and tried to keep my feet in,'' Johnson said. ``It was like a balancing act. It looked like it was far out of bounds, and I just tried to keep my feet in and catch it.'' The catch gave Penn State (3-4) a 24-7 halftime lead. ``One of our goals is to never give up scores at the beginning or end of the half, but I still felt good at halftime,'' Southern Miss coach Jeff Bower said. ``I thought all we needed was a three-and-out to start the second half and we would have been in good shape.'' They wouldn't get it. Mills followed that up with a 42-yard touchdown pass to Tony Johnson on the first possession of the second half. Just 47 seconds later, Penn State went up 38-7 when Larry Johnson _ Tony's older brother _ blocked a punt and returned it 40 yards for a TD 2:14 into the third quarter. It was Larry Johnson's second touchdown off a blocked punt return this year.
