Unseeded Samuel Shropshire pulled the upset of the day, defeating third-seeded Stefan Kozlov, Pembroke Pines, Fla., 6-4, 7-6(5) in a boys 18s third round match. Shropshire, who is from Philadelphia, had two match points in the second set, but Kozlov fought off both of them. “I had one shot I thought was in and I started to do a little “Come on,” but it was called out, which it was,” said Shropshire, who is headed to Northwestern University in the fall. It’s always difficult to come back from that. I thought to myself, if you keep it together you can still win the tiebreaker.” Kozlov was broken on his first two service games of the match.
