The Tar Heels are 2-2 in overtime this year and 6-9 in the past four years.
"It's not easy to play seven-a-side for an extra 30 minutes," said UNC coach Karen Shelton. "I know, I've done it."
In field hockey, overtime is a lot like soccer. They play two 15-minute sudden-death periods with only seven players, followed by a penalty stroke shootout where the goalie and player face each other one-on-one.
"I do keep my best players in there, though," Shelton said. "That's my philosophy as a coach, keep the best kids in there and let them win or lose."
This weekend the Tar Heels played two double overtime games, beating Duke 5-4 on Saturday and losing to Kent State 2-1 on Sunday.
"We haven't (played in overtime) for a while and we haven't practiced it for a while, so I think yesterday helped today," Shelton said. "Compared to (Saturday), the overtime today was so much better."
Even though Shelton and the team said they played better in overtime Sunday, they lost the game on penalty strokes.
But this is not surprising -- UNC is 3-7 all time in games that go to penalty strokes.
"Usually when you play the seven-a-side with two periods like that, one team breaks down because of fitness, so it very rarely goes to penalty strokes, so I don't spend a great deal of time at practice on that," Shelton said. "I think it's lack of preparation on my part, so I'll accept responsibility for that."
