"That slice is pure Federer!": Roddick fascinated by a transformed Alcaraz

Former world number one Andy Roddick still can't get over it: Carlos Alcaraz, once criticized for his serve, has become more than proficient in that aspect of the game. A spectacular evolution that the American attributes to the rising intensity of his rivalry with Jannik Sinner.
We rarely see Andy Roddick this enthusiastic. On his podcast, one of the greatest servers in tennis history revisited Carlos Alcaraz's US Open victory, highlighting a decisive improvement in the Spaniard's game: his serve. A shot that, in his own words, was once "far from the level of the best"... but has now become a formidable weapon.
"His first serve is getting more and more powerful. It's a completely different story for his opponents now. The way he uses the slice today is something different. It reminds me of Federer. I think he also drew inspiration from Dimitrov's match against Sinner at Wimbledon.
I think that match had an impact on his tactics, because he used that shot multiple times. Obviously, it's clear that his serve has improved significantly compared to the past. His serve is becoming increasingly powerful and effective, which isn't fun for the rest of his opponents." Comments reported by Punto de Break.
