An undefeated Yale swimming team, aiming for its 46th straight victory, will take on Hal Ulen's decidedly underdog outfit at 4:30 this afternoon in the Blockhouse.

The experts say Ulen's squad doesn't stand a chance.

Yale now rests in first place in the Eastern Intercollegiate Swimming League with 6 wins and no defeats. It had an easy time beating Dartmouth 42 to 33, almost the same margin of victory that the Indians had over the Crimson.

The Blue should place most of its men in the individual championships at Princeton next week, and is heavily touted to win the nationals over Ohio and Michigan later this spring.

Against this powerful threat Ulen can only hope for a reversal of the time-clock evidence.

Possible Winners

Win Briggs could run up points in the dive, Ted Norris stands a good chance to win the 440-yard freestyle, and Chuck Hoelzer could conceivably win in the 200-yard breaststroke. Any other figuring is worthless from this point on.

Yale boasts a strong set of freestyle men, headed by Ray Reid, frequent winner in both the 100 and 50-yard races, and including Don Erwin, Emil Estoclet, and Larry Munson. Against these, Bob Borke, Mort Hull, Jerry Gorman, Bill Mac-Vickar, and Shep Brown will have to show better than their very best stuff.

If Bob Kiphuth decides to "load" his 300-yard medley relay team with Floyd Aglietti, Bill Osbourn, and Dick Baribault--as he did against Dartmouth--the race looks like a sure Yale victory.

In the backstroke, the Eli's boast Mike Pettee, consistent winner and one of the East's speediest men in the event. And Pettee has himself been beaten by teammate Al Ratkietwich. From the Yale point of view this race should be Harvard is now tied for third place in the Eastern Intercollegiate Swimming League. It's not going any higher.

Freshmen in Preliminary

With an undefeated record this season--like their elders--the Yale freshmen will be favored over Bill Brooks' Yardling swimmers when the two teams meet at 3:30 this afternoon in the Block-house pool.

The Elis have successfully coped with Andover, Exeter, and the Dartmouth freshmen, the only three teams which have beaten the Crimson. The Yardlings have four wins to their credit.
