Supenb pass defense and an excellent substitute performance by Eric Crone pushed Harvard to an astounding 14-12 upset over Yale to give the Crimson a second place tie with Yale in the Ivy League standings.

After a scoreless first period, Harvard scored two second-period touchdowns and never trailed thereafter.

Both Harvard and Yale ended their seasons with 7 and 2 records.

Dartmouth won the Ivy League title today b dumping Pennsylvania.

The Harvard victor enabled John Yovicsin to achieve his third-best record as Crimson coach. Only his 8-0-1 in 1968 and his 8-1 in 1966 were better.

The wind was blowing steadily from the northwest at 25 m. p. h. with gusts of 35 m. p. h. Harvard coach John Yovicsin tested the wind just before game time by throwing a clump of grass into the air. After swirling around his head seven times, the grass blew up into the colonnade.

The passing and kicking games of both teams were severely hampered by the wind, which added another headache to Eric Crone's already congested nervous system.

Yale won the toss, but elected to kick and take the wind. The kickoff was short and fullback Tom Miller brought it out to the 32-yard line.

On the second play from scrimmage, Crone fumbled the snap from center at the 34-yard line, and after the ball slipped away from halfback Ted DeMars, Yale recovered.

The defense held, and on fourth-and seven place kicker Harry Klebanoff missed a field goal from the 38.

The two teams fumbled four times in the first six minutes of play, and the Crimson got a break when Mark Steiner recovered a stray pitchout from Joe Massey to tailback Don Martin.

Crone went directly at Yale's strength-the middle of their defensive line. With DeMars and Miller alternating on solid gains, the Crimson drove to the Yale 40. On fourth-and-ten., Richie Szaro punted and the ball went dead on the Yale nine.

The teams exchanged punts once more and the first quarter ended with Harvard driving from their own 41-yard line.

A short, partially blocked Yale punt gave Harvard excellent field position on the Yale 32 at the beginning of the second quarter. Crone completed his first pass of the game to Bruce Freeman on a crucial third-and-eight to give the Crimson a first down on the 20. Crone again responded to third-down pressure as he hit Freeman on the Yale 7.

On the next play, Crone faked beautifully to Miller up the middle, and flipped a swing pass to DeMars, who was all alone in the flat. DeMars walked into the end zone, and Harvard led, 7-0, after Richie Szaro booted the extra point with about ten and a half minutes to go in the half.
