No, I don't see that.
Looking at Gonzales' year in 1964, he won the Cleveland "World Pro Championships", the Jack March event, no longer pretending to be the U.S. Pro, over Gimeno.
A remarkable win at White Plains, the Golden Raquet at Wembley (not the big tournament), Knokke-Le-Zoute in Belgium, the Florida Pro (over Bartzen and Giammalva).
Gonzales did well enough to finish third overall for the 1964 tour of USA and Europe.
In 1949, he was 21 years old, and could run all day, outlasting Schroeder in the Forest Hills final and PSW final. He also beat Sedgman in the Davis Cup final.
These were his first mature wins against a top player.
Although he started slowly against Kramer on the pro tour, he gradually improved and had a substantial edge on the California portion of the tour, 8 wins to 4.
Gonzales won his biggest tournament meeting with Kramer in his rookie season in the Philadelphia final, the most important event of the season, 7-5, 6-3, 6-4. A no-doubter.
