UNIVERSITY PARK — As senior night performances go, it is difficult to imagine anyone topping Penn State’s Jamelle Cornley. Prior to Saturday’s game against Indiana at the Jordan Center, he enjoyed a standing ovation, a handshake and hug from head coach Ed DeChellis, and then a long, emotional embrace with his mom. During the game, he hit the final two shots, including a baby hook that gave Penn State a 59-58 lead and a dunk that accounted for the final score, 61-58. And after the closer-than-expected victory, he addressed the near-capacity throng of 15,035 that stuffed the BJC. It was PSU’s largest home crowd since 2001. ‘‘I want to thank you for your support and I hope you continue to support YOUR team,’’ Cornley said. On this night, however, it was clearly his team. Perched precariously on the NCAA Tournament bubble, Penn State hardly played its best game against a Hoosier outfit that had lost six straight coming in.
