The Harvard golf team continued its rampage of reversals with a clear-cut 5-2 win over Cornell at the Myopia Golf Club yesterday. The Big Red, which killed the Crimson, 6-1, last year, joined Williams, Boston College, Penn, and Brown on the list of teams which beat Harvard in 1966 but fell to the powerful 67 squad.

Harvard's strength at the bottom of the ladder was the decisive factor in yesterday's match. Tom Wynne, Bob Sinclair, and Roger Wales won at five, six, and seven, and were joined for the victory by captain Brain McGuinn at three and Bob Keefe at two.

Wales's victory, 4 holes up with 3 to play, was the biggest margin and should strengthen the junior's confidence at what will be a key position in upcoming matches. Sinclair boosted his individual record to 8-2 with a 3 and 2 victory, and sophomore. Wynne had no trouble, winning 4 and 2.

Mc Guinn's decision was by the same score and is final proof, if any was needed, that the veteran captain has recaptured the game that made him number one last season.

Keefe, whose victories at two have been impressively consistent, charged up the back nine with a string of birdies and climaxed his 2-up win by sinking a 40-footer on the 18th green.

Lopucki Drops Behind

Number one man Bruce Lopucki dropped four holes at the beginning of his round and couldn't catch up, losing 3 and 2. Paul Oldfield, who is usually strong on the greens, three-putted several holes and suffered a 2 and 1 defeat.

Both teams had to contend with strong gusty winds yesterday. The course is still n far from top condition, and holes 3 through 7 are under water and not playable. To compensate, the teams play 14 through 18 twice.

Monday the golfers compete in the Greater Boston Tournament at Concord Country Club, Postponed last Monday because of rain and snow, the tournament, in which Harvard finished third last spring, will be 18 holes instead of 36.

Next weekend, the hot-shooting team will fly to Penn State for the Eastern Championships before resuming its match schedule against the remaining Ivy schools.
