Four Crimson seniors who have never played on a team that lost a squash match close out their intercollegiate careers this afternoon when the unbeaten Harvard squash team faces Yale in New Haven.

Vic Niederhoffer, John Vinton, John Thorndike, and John Francis have played against some good Yale teams--two years ago Francis had to come back from a 13-6 deficit in the last game to give Harvard a 5-4 win. Last year the Elis won three of the top four matches only to lose 6-3.

But today's Yale match figures to be something of an anticlimax unless a massive case of overconfidence hits the Crimson. The Hetheringtons and Howes who led Yale teams to so many great seasons are gone, replaced by just three lettermen and a scattering of sophomores up from a freshman team Harvard pasted 7-2 a year ago. Yale has lost matches to Princeton and amazingly, to Cornell. Harvard squeaked by the Tigers 5-4, but routed Cornell 9-0.

The Elis are astoundingly weak at the top. Their number one player is Ralph West who was beaten by Dinny Adams in last year's freshman match. Adams is now playing number seven for Harvard.

West is backed up by a squad that has only one senior--number six man Ben Moyer--and a host of sophomores. The captain is junior number two man Bryce Appleton.

One Harvard senior probably won't be in the lineup today. Lou Williams, top player on the unbeaten freshman team three years ago, number two man on this year's squad, still is not back in shape after a wrist injury suffered in a car crash several weeks ago.

Coach Jack Barnaby had hoped to use Williams in the unofficial tenth match, but the senior probably won't be able to make the trip.
