Give all the credit in the world to Angelique Kerber - great, great talent. She's been in the top 10 for the last four years, and she's one of those players that just really had a difficult time, when the chips were on the table, to kind of bring them over. And this time, she did it. I'm really happy for her because these chances don't come for these other players. Serena Williams has got 21 grand slam champions. Angelique Kerber was in her first final.
