LAKE CARNEGIE, N.J. -- Seventh-ranked Princeton fought off a comeback attempt by No. 11 Yale on Saturday to retain the Eisenberg Cup during the 40th renewal of the rivalry and continue its progression toward the 2014 Ivy League Championships.

In a regatta that faced challenging headwinds as the racing progressed, the two historic Ivy League programs had several competitive showdowns, including a thriller in the varsity four competition.

Princeton won its fifth straight Eisenberg Cup in 7 minutesm 3.8 seconds, while Yale's big push in the middle of race fell short in 7:06.4.

"The varsity race was a really good one," said head coach Lori Dauphiny. "Princeton got out on the start, but Yale made a big push back in during the middle. They almost drew even. Princeton was able to respond and push out a little again. It was a good, tough fight for both."

The second varsity kept its perfect season alive with a win by more than eight seconds, while the varsity four nearly pulled off a wild comeback win.

"The four was one of the most amazing races," said Dauphiny. "They were down by open water, and then they came back. It was a really rough first half, but they really seemed to come together in the conditions and started moving."

As both Princeton and Yale move closer to the Ivy League Championships, it continues to look like the league is as deep and strong as ever. While top-ranked Brown has earned the distinction as favorite right now, there is plenty that could change over the next few weeks.

"It is tightly packed, and Yale probably has had less time on the water than us," Dauphiny said. "I think you will see a lot of changes during the season. It’s hard to say, and it's really hard to measure people’s speed. Brown keeps doing well, and I do think there is favorite. But it is still a ways away."
