The vey worn ball on the right was used to set the Guinness World Record of 25,944 consecutive hits (over 14 hours, 31 minutes) for the longest rally - August 10, 2008 - by identical twin brothers Angelo and Ettore Rossetti . The worn ball in the middle was used by them in 2007 to try and set a new world record. Their 19,490 hits fell short, but did set a new American record. The ball on the left is a new ball, for comparison.
