PRINCETON, N.J. (AP) _ Ronald Jean rushed for 137 yards and three touchdowns while Phil Stambaugh threw for 267 yards and one touchdown as Lehigh beat Princeton 31-0 Saturday night.

In winning its 15th straight regular season game, the longest current streak in Division I, Lehigh (3-0) spoiled the first night game in the 130-year history of Princeton football.

The Mountain Hawks have outscored their opponents 136-17 this season, while Princeton (0-2) has yet to score a touchdown.

It was the Tigers' worst home loss since a 37-0 defeat to Northwestern in 1986, one year before Steve Tosches became head coach. This is also Princeton's first 0-2 start overall and 0-2 start at home since 1986. The Tigers' previous worst home losses under Tosches were two by 24 points in 1996.

Jean gave Lehigh a 7-0 lead with a 10-yard touchdown run late in the first quarter. The Mountain Hawks broke it open in the second quarter when Stambaugh threw a 12-yard touchdown pass to Brett Snyder, and Jean scored on a 3-yard run.

Lehigh added a 36-yard field goal by Jaron Taaffe and a 2-yard scoring run by Jean in the second half.
