UGA's Allison Schmitt pushed the United States in front in the anchor leg to win the 4x200-meter freestyle relay at the London Olympics on Wednesday.
Georgia swimmer Shannon Vreeland was also on the team.
"I'm just happy as heck for Shannon and Allison," said Georgia coach Jack Bauerle, who is in London. "Having two of the four ladies on the relay was a real point of pride for all of us. It was so much fun to watch the two of them swim the back half of the relay and get up on that medal stand. That was such a great relay. I could not be more proud of Shannon and Allison for what they did for Georgia and for the U.S."
The Americans clocked an Olympic-record 7 minutes, 42.92 seconds.
Australia led by a half-second entering the anchor leg but had to settle for silver in 7:44.41.
