In the first match of the day, the girls team frittered a halftime lead of 20-12 to end up losing 36-57 against Africa.
The boys, in India's last engagement of the day, met with similar fortunes as they wasted a 15-point advantage at the break to lose 41-51 against Europe and Middle East.
In between these two matches, India boys and girls were thrashed 21-63 and 23-62 by Africa and Europe and Middle East respectively.
While the boys finished third in the four-team group also comprising Latin America whom they beat on Wednesday the girls remained winless from three outings, finishing last in the pool.
This being a tournament where teams from across the globe get a chance to play in the best facilities and rub shoulders with their US counterparts, every team in the international bracket is given a chance to play in the single elimination round, which is on Saturday, where India boys and girls will take on their Canadian counterparts.
After a forgettable outing against Africa, the Indian boys were off to a flying start against Europe & Middle East. While the first quarter went to them 20-8, the second quarter was won by a scoreline of 10-7 as India went into halftime with a healthy 30-15 lead.
Forward Kushal Singh, who ended with 15 points, starred for the India U-14 team with his stylish 3-pointer in the second quarter being the highlight.
It looked like a disappointing day would end on a high but just like the girls, it all fell apart from the third quarter where India managed just five points to Europe & Middle East's 20 as the quarter ended in a 35-35 tie.
India did not score a basket for almost 10 minutes before Lokendra Singh scored with 4. Twenty-four minutes left on the hooter in the final quarter which was dominated by Europe & Middle East as they racked up 17 points to India's six and seal the deal 52-41.
Coming to the U-14 girls, they picked themselves up well after a torrid performance on Wednesday against Latin America to take a 20-12 lead at halftime. It was a cagey affair till Muskan Singh scored two points with a pullup jump shot to help India nose ahead 11-10 from being down 9-10.
Shomira Bidaye cashed in on the momentum with a brilliant 3-pointer to make it 14-10 as India finished the second quarter with an eight-point lead. Besides Muskan and Osheen, Jeevika Kumar also did her bit with a 3-pointer in the second period.
But all hopes of a memorable win nosedived post the breather as the Africans bounced back in style riding Elalfy's individual brilliance.
Africa pulled back to level at 27-27 after Elalfy converted a pair of free throws and Kadidia Traore added another point with a layup shot. Africa finished with 24-9 in the third quarter and killed the contest in the fourth with another dominating 21-7 as they won 57-36.
In their next match, Europe & Middle East were too strong for the Indian girls.
