Harvard's Yardling football team employed a powerful ground attack and perfect execution to roll to a 50-13 victory yesterday afternoon over the winless Brown freshmen.

The win was the Yardlings' first since the season opener against Columbia and snapped a three-game losing streak.

For once, the Crimson offense executed flawlessly, and the result was a healthy 34-7 halftime lead. The only thing that could halt the Yardling onslaught was the clock: quarters were shortened from 15 minutes to nine in the second half.

Scoring twice and rambling 86 yards on 13 carries, halfback Richie Gatto led a Crimson rushing attack that plowed through the mud at Brown's Moses Brown Field for 319 yards.

Quarterback Rod Foster, in his first starting assignment, sped 43 yards for the game's first touchdown, and later passed 13 yards to Gatto for a score.

Harvard was ahead, 14-0, at the end of the first stanza after Foster's run and a 12-yard burst by fullback Steve Hall. Ted DeMars and Kevin Murphy scored on runs of 35 and 28 yards, and Gatto hauled in Foster's aerial to complete Harvard's first-half scoring.

Hall blasted two yards in the third period for a tally, and Gatto sprinted 26 yards in the last quarter to pad the Crimson lead.

Brown found all of its limited success in the air, as the Bruins passed for a 14-yard touchdown just before halftime and a four-yard score in the third quarter.
