Abby Wambach scored her 156th career international goal to move within two of Mia Hamm's U.S. women's record in the Americans' 4-1 victory over South Korea on Saturday night at Gillette Stadium.

Wambach scored on a penalty kick in stoppage time after Alex Morgan was fouled inside the area.

Kristie Mewis opened the scoring in the third minute with her first international, and Lauren Cheney scored in the seventh minute. Cho Shoyun scored for South Korea in the 26th, and Carli Lloyd made it 3-1 with a 30-yard blast in the 57th minute.

The United States is unbeaten since March 2012, going 29-0-4, and is 8-0-2 on the year. South Korea is 3-4-1 this year.

The teams will meet again Thursday night at Red Bull Arena in Harrison, N.J.
