The gold medal was the first international title for Loss, who became the first Team USA member in the last three years to earn a place on the top of the podium at a Men's Junior Saber World Cup.
"It has taken a lot of hard work and a lot of support from my coaches, my team and my family to get here," said Loss on winning his first international title. "I am very excited for the next few years, both for myself and for Columbia. We have a very strong team at the moment, and I expect we will be winning some NCAA titles over the next few years. I am really looking forward to being able to be a part of it and bringing home (hopefully a lot more) wins for Columbia."
In the table of 64, the first-year defeated Kohei Ando of Japan, 15-9, to move onto the table of 32 where he edged George Iancu of Romania, 15-14. Loss then dueled his way to a 15-11 victory over Nicolai Zaporojcenco of Moldova, becoming the sole Team USA member to advance to the quarterfinal round.
Competing in his first quarterfinals at a Junior World Cup, the Laguna Beach, Calif. native won his next match against Oleksiy Statsenko (Ukraine) by a score of 15-13, and continued to roll with a 15-13 semifinal win over Sandro Bazadze (Georgia) to earn a shot at the gold.
In the finals, Loss battled Kostiantyn Voronov in front of the Ukrainian's home crowd, but did not falter as he put together a 15-12 victory and brought home the title.
For Dubrovich, the bronze was the first Junior World Cup medal for the two-time Junior World Team silver medalist.
"It feels great to win third place in Luxembourg," said Dubrovich. "I am so proud to represent Columbia fencing. We have such a strong team with some of the best fencers in the country and we are all ready for the upcoming season. I have always wanted to fence for the Columbia Lions, and this year, I have a really good feeling in terms of the results we can achieve. All of us work extremely hard and are dedicated to winning Ivy Leagues, and I know we have a great shot at doing so."
The first-year posted a 5-0 result in the pools on Sunday, earning a bye into the table of 64 as the seventh seed, during which she defeated Leandra Behr of Germany by a score of 15-3.
In the table of 32, Dubrovich quickly built up an 11-0 lead within the first two minutes of her bout against Martyna Przybylowicz of Poland, who made a brief comeback before Dubrovich won, 15-7.
Dubrovich then earned a 15-6 victory over 2012 Cadet World Team member Sabrina Massialas of San Francisco, Calif. In the quarterfinals, Dubrovich led from start to finish against 2011 Cadet World medalist Martina Sinigalia (Italy) and advanced to the semifinals with a 15-9 victory.
Dubrovich fought until the end as she faced another contender from Italy, Francesca Palumbo, in the semifinal round, but Palumbo took the victory, 12-8.
