Serena Williams loses one game in Madrid Open first-round win

Serena Williams dropped just one game in her first-round victory over fellow American Madison Brengle at the Mutua Madrid Open this afternoon.

The top seed took just 22 minutes to claim the opening set as she raced to a 6-0 success.

Brengle saved five break points in the opening game of the second before getting on the board, but it would be her only game as Williams reeled off the next six to book her place in round two.

She will face another American, Sloane Stephens, in the next round.
