PRINCETON, N.J. (AP) _ Garrett Kreitz sank a clutch free throw with 7.2 seconds left to give the University of Pennsylvania a four-point lead at 57-53, sealing an eventual 57-55 Quaker (2-5,1-0) victory over the Princeton Tigers (7-5,0-1) Saturday night.

Kreitz's free throw derailed Princeton's impossible eight point comeback in the last half-minute of play. Down 45-55 with 0:27 left, Mitch Henderson sank a baseline three-pointer to spark an 8-1 run in only 20 seconds.

Brian Earl followed with another three with 16 seconds left, bringing Kreitz to the line with 7 seconds on the clock. Earl tipped in a missed jumper at the buzzer, but the extra two weren't enough and Princeton fell 57-55.

Abysmal shooting from the free throw line kept the Tigers in the game, as the Quakers only sank two of ten shots from the line in the final minutes.

``As the lead dwindled, we weren't worrying about making two foul shots, but one. Finally it came down to the point where one foul shot would win the game,'' said Penn center Tim Krug.

Depite a 0-5 performance at the line, Quaker guard Donald Moxley dominated beyond the arc, sinking 3 of 4 for a game-high 19 total points. Tim Krug provided consistent inside play, adding 14 points and 9 rebounds.

Mitch Henderson was the only Princeton player to score in double digits, sinking three treys for a team-high 15 points. Pennsylvania held Princeton's freshman star Brian Earl to only eight points, five of which came in the last two minutes.

``We've got to find a way for my guy Earl to get more than four shots a game,'' said Princeton coach Pete Carril. ``We're not setting good screens for him.''

In contrast to the frantic final minute, both teams were lethargic and off target for the first half. The Quakers slowly pulled ahead to a 22-15 lead by the buzzer on Nat Graham's early 8 points. Tight Quaker defense held a shaky Princeton offense to 26 percent shooting from the field.

``I'm not sure we could have played better defense in the first half,'' said Pennsylvania coach Fran Dunphy.

This victory maintains the Quakers 44-game winning streak in the Ivy League and is their seventh consecutive win over Princeton.
