Harvard's squash team has everything to win and everything to lose at Princeton tomorrow.

If the Crimson wins big, it will beat out Navy for its sixth straight national intercollegiate championship.

If the Crimson loses to Princeton, which dealt Harvard its only loss last year, 5-4, it will also lose the Ivy League title.

Harvard coach Jack Barnaby doesn't forsee either of these fates for his team. "We've got to be favored over Princeton," Barnaby said last night, "but I'll be somewhat surprised if we take the championship from Navy."

Navy is heavily favored to beat Army in Annapolis, and since composite scores determine the national championship, Harvard's hopes rest on outscoring the Midshipmen in tomorrow's matches. The Crimson lost to Navy, 6-3, earlier this season, but beat Army, 8-1.

Barnaby will make no changes in his veteran lineup, which has Anil Nayar, Jose Gonzalez, and captain Craig Stapleton in the top three positions. Because injured number two man Rick Sterne has been lost for the season, sophomore Frank Hobbs will continue to fill in at the number nine position.

"Travel always means trouble in squash," Barnaby said. "We haven't had a good road trip all year. My only hope is that we've gotten used to adverse galleries and will be less likely to panic."
