Dom Repetto will probably pitch this afternoon as the Crimson nine sets out to settle a score against the Dartmouth Indians. Last year Dartmouth knocked the Crimson out of the E.I.B.L. race, 7 to 6, at Hanover, as Repetto lost to Dick Van Riper.

Today the invading woodsmen bring an undefeated record to Soldiers Field, as their 2-0 mark is the only pure slate besides Yale's. Repetto may oppose Van Riper again, but the more probable Green choice is righthander Ron Judson, whose fine curve ball is sometimes offset by a tendency to wildness.

Revenge will be one motive today, but a more important one is a chance at the Crimson's first E.I.B.L. crown in 18 years, and a victory today seems necessary for that aim, since two Yale defeats appear highly improbable.

This is a Crimson team with a first-rate defense and some brilliant pitching. Repetto has been masterful against Princeton and Brown, and Bob McGinnis was never better than against Holy Cross. Yet sometimes the pitchers don't find the spots, and on these occasions sharp defensive play has helped considerably.

The infield of Tom Bergantino, Bob Hastings, Bob Cleary, and Babe Simourian has been very steady and comes up with more double plays than one expects to see in college baseball. The fast outfield of John Getch, Walt Stahura, and Matt Botsford has also been quite dependable, though perhaps better on throwing than catching.

Big Phil Haughey behind the plate has handled pitchers excellently and presented an easy target, always staying in control of the game.

The team's hitting has been erratic. The Crimson climbs all over an incompetent hurler, and this makes batting averages somewhat deceptive, for the Greater Boston League figures are higher than the overall totals. Still, the team has been getting enough runs to win, and has come from behind several times.

This Crimson nine can win a title, but only by playing its best from here on out. The team knows it, and consequently must be favored this afternoon.

The freshman nine defeated Emerson, 6 to 3, yesterday.
