NEW YORK (AP) -- Kim Clijsters hit her last shot as a pro tennis player into the net. Doubtful anyone will remember that, though. Smiling right until the end in front of 2,800 buzzing fans on Court 17 at Flushing Meadows, Clijsters officially made her way into retirement Saturday night. She and mixed doubles partner Bob Bryan fell 6-2, 3-6, 12-10 to Ekaterina Makarova and Bruno Soares in a back-and-forth match filled with clutch shots, loud cheers, four saved match points and - at the end - no tears. ''It's surprising that I kept it dry, I haven't been crying,'' Clijsters said.
