Squash
It's the 2012 World Open final between two Egpytians and Mohamed El Shorbagy and Ramy Ashbour battled away for a full 53 seconds before El Shorbagy wins the point with a casual shot through his legs.
Tennis
Rafael Nadal was unstoppable at the peak of his powers. His winner in this epic 26 second rally against Fernando Verdasco in the semi-final of the 2009 Australian Open was both brutal and precise.
Badminton
By far the longest rally in our six that had its own controversy. Vietnam's Tien Minh Nguyen and Denmark's Jan Jorgensen smashed the shuttlecock at each other for a full one minute and 54 seconds in the quarter-final of the 2013 World Championships. Jorgensen then lets a close one drop that officials ruled was out but Nguyen disputed the call after battling so hard for one precious point.
Sepak takraw
A mixture of football, volleyball and tennis combined produced an exhilarating 13 second rally between Malaysia and Thailand in the 2014 ISTAF Super Series. With the ball sailing well of out play, Thailand's Somporn Jaisinghol returns it while colliding with a cameraman and the advertising boards. It was all vain as Malaysia won the point.
