Fifty parting thoughts from the U.S. Open
PRICE: Serena's commitment pays off with another U.S. Open title
• Paes and Stepanek went on to win the title, beating Alexander Peya and Bruno Soares 6-1, 6-3. Lucie Hradecka and Andrea Hlavackova won the women's title by eliminating Serena and Venus Williams in the semifinals and rallying from a set and break down to edge Ashleigh Barty and Casey Dellacqua 6-7 (4), 6-1, 6-4 in the final. The Australian runners-up were finalists at three majors this year.
• A tip of the backward baseball cap to Lleyton Hewitt, 32, for reaching the fourth round for the first time since 2006. But how will he abide losing a 5-2 lead in the fifth set -- and the last five games -- of his match against Mikhail Youzhny? Fascinating how even the most revered fighters and mentally strong players occasionally get "the bottles," as the Brits call it.
Thanks to everyone for the emails and tweets. We'll do it again for the Australian Open in January.
