LONDON: Carlos Alcaraz came through a testing first-round match against Adam Walton at Queen’s on Tuesday as the top seed returned to action for the first time since his dramatic French Open triumph. But two of the world’s top 10 crashed out as Americans Taylor Fritz and Ben Shelton lost to French duo Corentin Moutet and Arthur Rinderknech respectively. Alcaraz, back on grass for the first time since winning his second Wimbledon title last year, beat his 86th-ranked opponent 6-4, 7-6 (7/4) on a sweaty day in west London.
