OK, sure, maybe it wouldn't be rational to say there's no point in actually holding the full U.S. Open and instead just fast-forwarding to the inevitable matchup for the men's championship between Jannik Sinner — assuming he's healthy — and Carlos Alcaraz on Sept.

The two young champions, who met as teen-agers, are expected to face off at this year’s U.S. Open. A new book by Giri Nathan tracks their parallel ascent.

Carlos Alcaraz won the Cincinnati Open title in a little more than 20 minutes after top-ranked Jannik Sinner was forced to retire because of illness during the first set.
