Tennis: Three players from the Junior Tennis Champions Center in College Park will compete at the U.S. Open this week in New York. Frances Tiafoe, 18, who has surged up the ATP rankings to a career high No. 123 by reaching four ATP Challenger finals since April and claiming his first ATP Challenger title at the $100,000 Challenger Banque Nationale de Granby in Canada this month, will make his third Grand Slam main-draw appearance; he competed in the 2015 French Open and U.S. Open. JTCC's Denis Kudla, 24, fresh off representing Team USA at the Olympics in Rio de Janiero, also is in the main men's draw; this is the first year he has played in the main draw at all four Grand Slams. JTCC's Treat Huey, 30, will partner with Belarusian Max Miryni in men's doubles. JTCC's Usue Arconada, 17, lost Thursday in the second round of the Open qualifying draw, falling to 25th-seeded Sara Sorribes Tormo, 5-7, 6-4, 6-2 (25).
