Harvard's tennis team completes its home season this weekend, and the undefeated Neturen should blow Columbia and Navy right off the courts unless the Soldiers Field gust gets them first.

The Columbia match, at 2 p.m. today, should give Harvard its 11th straight win without much effort. Last season Columbia was 0-8 in the Eastern League, and this season the Lions are about the same, even though they have won one league match.

At number one, Columbia will have Steve Gottlieb, a tall left-hander who does not have the speed or control to match Crimson captain Dave Benjamin.

Harvard's Bernie Adelsberg will probably face Mark Naison in the second match. Naison, like Adelsberg, is a hard hitter, but he lacks the consistency of the Harvard sophomore.

Buzz Baumgold, another Lion slugger, faces Harvard's steady Clive Kileff at three. Columbia may have trouble winning at the top of the ladder, but they will have more problems at the bottom where Harvard is strongest.

The Navy match, here at 2 p.m. Saturday, will certainly not have the drama of last Saturday's duel with Princeton, but the Midshipmen could pull some surprises.

Harvard trounced Navy last year, 9-0, as the Middies had their worst season since 1958. With seven of eight lettermen returning this year. Navy is now a much deeper squad and chalked up an impressive 5-4 victory over Dartmouth--the team which pressed Harvard hard Wednesday.

In its top three positions, Navy will have Bill Burns, West Overton, and Captain John Williamson. The Middies can't quite match Harvard at either end of the ladder, but they are always in shape--and you never know when Kileff might run out of breath.
