Not positive about this but Alex Ibanez andd Johan(n) Sorozabal seem to fit the description. You can see both of them at the Amateur Basque Pelota Jai Alai Update Post I pointed you to a couple of days ago.
Alex Ibanez the red front in the 1st Division Final of the Xistera Kluba Cabanillas Finals on August 3 and is the blue front in the 2nd Division Finals of the Xistera Kluba St. Jean De Luz Tournament held on August 31. Note that the Sorozabal (red back) in the Aug. 31 match is G. Sorozabal, not J. Sorozabal.
Johan(n) Sorozabal is the red front in the 2nd semi-Final AND the blue front in the Final of the Tournois Couretepaille, also at St. Jean de Luz August 27 and 29. This was the amateur Tournament that was played before each of the Cesta Punta Pro Tour SLAM (Champion of Champion Tournament) won by Goikoetxea-Inza
Again, I'm not positive these are the guys, but they do seem to fit the descriptions.
If not, treat yourself to some pretty darn good Amateur Jai Alai anyway.
