On a temporary court erected under the ornate chandeliers in Grand Central Terminal’s Vanderbilt Hall, Amanda Sobhy became the first American-born player to reach the final of a World Series-level tournament on the Professional Squash Association Tour.

Sobhy, a Long Island native, lost in four games, 11-4, 9-11, 12-10, 11-8, to Nour el Sherbini of Egypt on Thursday night, but by finishing second in the $150,000 J.P. Morgan Tournament of Champions, she confirmed her status as one of the sport’s rising stars.

“Obviously I’m upset that it didn’t go my way in the finals, but I literally gave everything I had this week,” she said. “And I just fell short at the end.”

The loss capped a remarkable week for Sobhy, who is in her first full season as a professional after graduating from Harvard in May with a degree in social anthropology and global health, as well as four straight collegiate national championships. Sobhy, the 2010 world junior champion, is ranked eighth in the world — the first American-born man or woman to reach the top 10 — and was the 10th seed in the tournament.
