We all know that people have won 5 grand slams in a row in the open era. Bjorn Borg at Wimbledon and Roger Federer twice, at Wimbledon and the US Open. I'm not sure if anyone else has done 5 in a row in the open era but I don't think they have. So, will Roger Federer become the first man in the OPEN ERA to win 6 slams in a row at the US Open this year??? Thoughts.
