For  tennis, what is the longest rally for Both Mens and Womens singles?.
(In terms of 'longest' I would refer to back and forth strokes and NOT the time
 the rally lasted. I would like the answer to refer to only actual competion 
 tennis events.

Hi mongolia,

The following is the result of my research for records for the longest
rally in tennis.

"...The longest rally in tournament play was one of 643 times over the
net between Vicky Nelson and Jean Hepner at Richmond, VA in October
1984. The 6 hr 22 min match was won by Nelson 6-4, 7-6. It concluded
with a 1 hr 47 min tiebreak, 13-11, for which one point took 29
minutes. Will Duggan and Ron Kapp (both USA) performed a rally of
6,202 strokes, which took 3 hr 33 minutes, at Santa Barbara Municipal
Stadium, CA on 12 March 1988."

"Rob Peterson also holds a few other tennis records. Along with Ray
Miller, Peterson had a rally last 15,674 strokes in nine hours. The
two also hold the record for the longest rally with two balls and
2,789 strokes.

What was the longest ever tennis rally recorded?

"Research in the Library of Wimbledon Lawn Tennis Museum would suggest
that the longest rally in a tournament was one in which the ball
passed over the net 643 times. The competitors were Jean Hepner and
Vicky Nelson at Richmond, Virginia USA in October 1984. Nelson went on
to win the match."

"15,674 by Rob Peterson and Ray Miller of USA set Feb 5, 2000 San Diego Ca....."

also reference to a Rob Peterson (USA) managing 15,674 shots in 9hrs

Dear Rainbow 
Thank you for your very interesting answer. I would have expected much 
smaller mnumbers (certainly less than 100)
Both rallies sound as if they were 'staged' especially the one with 15674
strokes. (however I guess that's another question !) 

Kind Regards
