Alexander Zverev took another step towards winning his elusive grand slam title as he held off a rapid start from the breakout teenage star Rafael Jódar to return to the semi-finals of the French Open with a 7-6 (3), 6-1, 6-3.The past few weeks have had little precedent in the recent history of men’s tennis, with so many of the top players suffering early upsets in Paris. As the dust has begun to settle on the early losses to Jannik Sinner and Novak Djokovic, the second seed Zverev has emerged as the player most likely to win the title.Jódar, the 27th seed in Paris, has been one of the revelations during this clay-court season, and he entered the match leading the ATP with wins on clay this year, compiling a 19-3 record with quarter-finals in Madrid and Rome before his maiden grand slam run here. He gave an impressive demonstration of his clean, destructive shotmaking early on, demolishing the ball off both wings and pinning Zverev far behind the baseline as he established a 5-2 lead.However, normalcy resumed quickly. Jódar’s attempts to serve out the set ended in a break to love for Zverev, who took control and refused to relinquish his position until the end of the match. Zverev offered the Spanish teenager little room from then on, serving extremely well and attacking freely as he rolled through in straight sets.Zverev will face the winner of the late quarter-final between two other youngsters in the 20-year-old 26th seed, Jakub Mensik, and 19-year-old João Fonseca, the 28th seed.
