Steve Johnson of the United States beat fourth-seeded Richard Gasquet 7-6 (2), 6-2 on a rain-hit opening day of the Wimbledon warmup tournament at Queen's Club on Monday.

In a match that was delayed and then interrupted several times by rain, Gasquet held a set point but failed to serve out the opening set at 5-4.

After being overwhelmed in the tiebreaker, the Frenchman surrendered an early break in the second set and failed to recover.

All the other main draw matches were postponed.

The tournament features four of the world's top 10 players as they prepare for Wimbledon, which begins June 27.
