Protecting a slim lead after the first two days of the Women's Eastern Seaboard Championships at Blodgett Pool, Princeton splashed past Pittsburgh and Penn State in the meet's final day Saturday to win the title comfortably.

The "big three" schools duplicated their finish in last year's meet, but Harvard's swimmers improved to fifth, up four spots from 1981, in a field which annually members 30. Another Ivy school, Brown, finished fourth.

Pittsburgh's Jan Ujevich, only a junior, emerged as the meet's highest individual scorer by winning the 100-yd individual medley in 59 27, and adding a third place in the 100-yd freestyle.

Ujevich had captured three other individual titles on the first two days--the 50-yd freestyle, 200-yd individual medley, and 100-yd breaststroke.

Deep Tigers

But while Pittsburgh relied on Ujevich and Amy Jackson to score in event after event, Princeton fell back on superior depth, consistently picking up seconds and thirds in races the Tigers could not win.

The Tigers took command of the final day's action in the very first event as Liz Richardson and Diana Caskey ran one-two in the 1650-yd freestyle. Betsy Lind scored a second for Princeton in the next race, the 100-yd freestyle, and the trophy was on its way back to New Jersey.

Harvard did not succeed in moving from fifth to fourth as Coach Vicky Hays had hoped, although four Crimson divers placed among the top 14 in the three-meter event.

Freshman Jennifer Goldberg, who finished second on the one-meter board on Thursday, again ran one place behind Penn State's Mary Ellen Clark on the high board.

Calvert Stars for Harvard

Harvard's highest scoring swimmer, junior Shelby Calvert, came home fourth in the 1650-yd freestyle. The distance specialist had also run third in the 500-yd freestyle on Thursday.

Two meet records came out of yesterday's action, noticeably fewer than Thursday or Friday, when new records were set in almost every event.

Sindee Simon of Yale, who had set one new mark in the 100-yd backstroke, did the same in the 50-yd backstroke with a 27 57.

Pittsburgh's Jackson shattered her teammate Ujevich's record in the 100-yd freestyle with a 51 10 Ujevich finished third in the event with a 51 87, a time that did not match her old record of 51 48 set last year.

Ujevich also missed another of her old meet records when she clocked 59 27 in winning the 100-yd individual medley last year in Pittsburgh, she finished in 58 84.
