They were the only black mark on Cornell's resume.
The only thorn in the Big Red's side in their quest for a perfect Ivy season last year.
And the Penn men's lacrosse team wants to get a reputation for that again as it looks to become No. 1 Cornell's first league - and overall - loss of the season.
"You can't ask for a better opportunity for us," coach Brian Voelker said. "It's a big-time chance for us to get back [after losing to Harvard]. To play the No. 1 team in the country and beat them - anything can happen."
The Quakers don't need any convincing. Last year, they went on a 5-0 run in the second half under monsoon-like conditions at Franklin Field and held on for the 8-6 win.
But overtaking the Big Red this time won't be easy. Penn (4-3, 1-1 Ivy) has struggled through three overtime contests, emerging 1-2 from them, while the Big Red (6-0, 1-0) have cruised through their schedule with a 7.5 goals-per-game margin of victory.
The senior duo of Eric Pittard and David Mitchell run Cornell's attack, netting 15 and 16 goals on the season, respectively.
Pittard boasts a blistering .517 shooting percentage, the best on the squad of players taking more than 20 shots. He contributes to Cornell's 2.5 goals per game, 13th in the nation.
Max Seibald, a preseason All-American, leads the charge up the middle. Last year's Ivy Rookie of the Year, he's described by Voelker as someone who "creates a lot of havoc in the field."
As a whole, Cornell "moves the play very well on offense," said Voelker. "There's not just one guy you need to focus on."
Cornell's defensive platoon isn't anything to take lightly either.
In goal awaits Matt McMonagale, who sports a .617 save percentage and just 36 goals allowed.
In order to pull off the upset, Penn will have to use its own weapons and exorcise some demons along the way.
"In all of our games, we've had a lot of lapses," Voelker said. "We've played well for two quarters in many of our games. We can't do that against this team."
Attacker Craig Andrzejewski is one of the best in the country at 4.14 points per game and Chris Casey has been solid at the starting role between the poles.
The Big Red will be looking to start their season 7-0 for the first time since 1987, while Penn wants to avoid another loss in Ithaca. Cornell has dominated in the teams' last two meetings there.
But for Voelker, everything changes when the opening whistle blows.
"It's who shows up and plays well," he said.
