=-> "In a phone conversation on May 14, at 21:46, the two discuss the Giro stage to Maielletta, won by Basso. Fuentes allegedly said in a 'wink wink' tone, "
A stranger won, Basso, Ivan Basso." Labarta responded, "A certain Ivan Basso." After that stage, Basso and José Enrique Gutierrez Cataluna (a Dr Fuentes client) were lying first and second on the general classification. Labarta: "
Well done boy, first and second with a certain Basso and a certain Guti." Fuentes: "Good heavens." Labarta: "Hey...first and second."
=-> "On the previous day (May 13), Labarta called Fuentes at 20:02 and spoke about the great performance of the "Buffalo" - Gutierrez' oft-used nickname - who finished fourth in stage 7 on that day. A surprised Fuentes said, "Buffalo?", to which Labarta responded in the affirmative,
also listing the stage placings behind Rik Verbrugghe: "Savoldelli [2nd - ed.], yes, and behind at 16 seconds,
Birillo arrived with Simoni,
at 20 seconds Zapatero [who was identified as Scarponi], at 24 seconds, Uno [La Gazzetta claimed it was Unai Osa, but he finished at 34 seconds - ed]. All very well. I want to say that all those who you are looking after, or who you are interested in, are in the race and also doing well." In addition to Basso and Simoni, only Rebellin and Gonchar finished at 16 seconds on the seventh stage. Both those riders, as well as Simoni and Savoldelli, have been excluded from having any connection with Dr Fuentes."
