PHILADELPHIA — In less than 24 hours, the season-long grip that Harvard held over the Ivy League slipped away.

Looking to bounce back from a loss Friday night at Princeton, the Crimson appeared sluggish and sloppy at times, and clutch and determined during others. Ultimately, an early double-digit hole proved too steep to overcome. They tried, getting as close as 2 points in the closing seconds, then launching a 23-foot 3-pointer at the buzzer that would have forced overtime. It missed, the final play of a 75-72 loss to Pennsylvania on Saturday at the Palestra.
