Joao Fonseca recently emerged as a remarkable young talent to watch. As a rising star, Fonseca has quickly garnered attention for his dynamic play style, powerful ground strokes, and the unique choice of racket that complements his game.
According to the talk tennis forum user Conrado85, that posted pictures of his racket being measured, he is using an older prostock version of the V-Core 98, with quite heavy specifications, but a lover swingweight. As seen, he also uses leather grip. The specifications amount to 356 g and 335 SW strung, with overgrip and vibration damper. The specifications in the pictures are without overgrip and dampener, so I calculated the specifications. The balance point is estimated, as it was not measured. Right now, he doesn’t put any lead in the throat or the sides of the racket, but specifications are probably still around these numbers.
Similar specifications to what Andrey Rublev uses, and it shows with his very heavy forehand, definitely something that these kinds of racket and specifications facilitate.
