Carlos Alcaraz defeated American Tommy Paul in straight sets 6-4, 6-4 to reach the quarter-finals of the Miami Open.
The 19-year old showed real class and superiority as he overwhelmed Paul in most of the key factors.
The US Open winner needs to win this trophy if he were to retain his number one position in the rankings.
A potential triumph in Miami would mean accomplishing the so-called “Sunshine double”, after his win at Indian Wells earlier this month.
Alcaraz will face another American in the last eight, Taylor Fritz, who overcame Denmark’s Holger Rune also in straight sets 6-3, 6-4.
In the women’s draw Elena Rybakina progressed effortlessly to the semi-finals after beating Italy’s Martina Trevisan 6-3, 6-0. The Kazhakh player remains unbeaten in 12 successive games, while she is also in pursuit of the “Double Sunshine” after her success at Indian Wells in California.
