The first match of the day was close until the end, as Brian Chen of North Carolina and David Giandomenico of Florida posted a best-ball score of 5-under-par 67. They defeated the International team of Victor Sanchez of Mexico and Manuel Girona of Spain by four strokes. Both teams opened with a 1-under-par 35 on the front nine and were knotted up through 12 holes, until the United States team picked up a stroke on each of the next three holes. They finished with a pair of birdies on Nos. 17 and 18 to give the United States team an early 1-0 lead.
The American Girls 13 team wasted no time jumping out to a lead, as they birdied No. 1 and watched the International team bogey. Those two strokes were the difference at the end of the day, as the even-par 72 posted by Haley Moore of California and Kendall Griffin of Florida bested the 2-over-par 74 from Michelle Ching Suet Lee of Hong Kong and Andrea Uribe of Mexico. Lee and Uribe were down in the match by four strokes after five holes, but scratched back to within a shot after No. 17. A bogey at the last hole dashed their hopes of evening the competition, as the Americans jupmed out to a 2-0 lead.
Carlos Marrero of Venezuela and Sean Doyle of Ireland put the first International point on the board with a 3-under-par 69 in Match 3. The pair played nearly flawless golf, recording three birdies and no bogeys for the round. Spencer Alexander of Florida and Spencer Cross of Tennessee carded a respectable 1-over-par 73, but were no match for the bogey-free International team. The point drew the International team back within a 2-1 deficit.
Match 4 brought the International team the opportunity to square the competition at 2-2. Max Clift of Canda and Rosswell Radoslaw Sinclair of South Africa swapped leads with Brett Barron of Georgia and Kitwana Ashford of Michigan all morning, deadlocking for the final time through 15 holes. A birdie on No. 16 put the International pair ahead for good, as an American bogey on No. 18 sealed the deal for the International team. Clift and Sinclair posted a 3-under-par 69 to the Americans' 1-under-par 71, knotting the competition at 2-2.
With the Teen World Cup amounting to a best-of-5 competition, Match 5 was crucial for momentum heading down the home stretch. Girls 14 winner Maria Balcazar of Mexico and co-runner-up Gabriella Coello of Venezuela may have seemed to have an edge based on the previous three days of competition, but Addison Mitchell of Arkansas and Megan Munroe of North Carolina were not to be denied. Mitchell and Munroe recorded 16 pars and two birdies on the day for a 2-under-par 70. Balcazar and Coello kept pace for the first nine holes, but fell behind with a bogey on No. 10 and never came back. The point gave the United States a 3-2 lead.
Match 6 came down to the wire, as Daniel Piceno of Mexico and Kyle Gorospe of Canada staged a back nine comeback against Matthew Ruel of Florida and Spencer Ralston of Georgia. Ruel and Ralston opened up a three-shot lead through nine holes, but three back nine birdies for Piceno and Gorospe brought them within a stroke heading to No. 18. An International birdie putt to square the match just missed, as the Americans earned their fourth point with a 2-under-par 70, putting them one point away from winning the Teen World Cup.
There was no stopping the tandem of Tyler Moore and Jacob Solomon, both of California, as they combined for a best ball score of 7-under-par 65. Solomon made eight birdies on his own ball, ensuring that there would be no opportunity for Roberto Jose Rojas of Costa Rica and Chris MacDonald of Canada to catch them. The International pair posted an impressive 4-under-par 68, but were still three strokes behind at the end of the day. With the point, Moore and Solomon ensured that the Americans would win the Teen World Cup.
Although the outcome of the Teen World Cup had been decided by the time Match 8 concluded, the play was impressive from the Girls 15-18 division, as both teams finished in the 60s. Girls 15-18 champion Kelly Whaley of Connecticut and Anna Buchanan of Georgia combined for a 5-under-par 67, while Margine Arguello of Panama and Yasemin Sari of Turkey posted a 3-under-par 69. Whaley and Buchanan recorded six birdies along with a lone bogey for the lowest girls score of the day. The U.S. team went up 6-2 with the point.
What appeared to be a blowout early on ended up being one of the closest matches of the day, as David Mackey and Benjamin Shipp, both of Georgia, held off a strong charge from Andres Caballero Perez of Mexico and Panat Bodhidatta of Thailand. Mackey and Shipp opened up a six-stroke lead on the International pair through five holes, but Caballero Perez and Bodhidatta scraped back with an eagle on No. 8 and birdies on Nos. 9, 15 and 16 to move to within two shots of the lead. A bogey on No. 18 for the Americans narrowed the gap to one stroke, but the International team was unable to birdie to force a draw. The United States won the 2012 Teen World Cup 7-2.
