The powerful Harvard freshman baseball team shelled Boston University for 16 hits yesterday and rolled to an over-whelming 20-0 victory here. Pitchers Curt Tucker and Bill Meyers combined to deny the Terrier pups even a single hit in the seven-inning game.

Today the Yardlings play Brown at 3 p.m. on the field next to Soldiers' Field.

A 350-foot triple by catcher Pete Varney and two singles off the bat of Chico Garcia paced the Crimson starters to a 14-0 lead before they were repleced after four innings. The pace did not slow up when the second string came in. Ray Stitch hit a home run and Brad Fenton tripled before the hapless B.U. frosh bowed in the oncoming darkness.

The Crimson totaled 16 hits--13 of them singles--and committed only one error in the field. B.U., hitless, committed seven fielding errors.

The freshmen so far, paced by the power hitting of Varney, Bill Kelly, Dan De-Michels, and Larry Cetrulo, are undefeated. In four games they have scored 50 runs to their opponents' nine.

The toughest contest so far has been against Exeter, which bowed 10-8 last Saturday.
