In the Leiter Cup baseball series yesterday afternoon, the Caveat Emptors defeated the Down and Outs, by the score of 4 to 1.

At 4 o'clock this afternoon, the Alphas will play the Mugwumps in the first of the semi-final games on the east diamond at Soldiers Field; and the Incognitos will play the Backwoodsmen on the west diamond. The winner of the last game will play the Caveat Emptors in the second semi-final match next Monday.

On account of the game with Princeton and the dual meet with Yale, no games will be played tomorrow afternoon. The final game in the series will probably be played next Wednesday.
