She somehow gets out the game! Iga Swiatek holds after Madison Keys nets again.
This next game is huge. Where will Keys be mentally as we tick into hour number three?

Yeah, I did that backhand a disservice with my description. It was very, very good.
Back to the action and Maddison Keys gets to 15-30, but looks to be losing the next point as she tosses a return up into the air. Out of nowhere though Iga Swiatek misses the overhead smash. Two break points.

Former Wimbledon champion on BBC 5 Live and BBC SoundsThat's the best backhand of the match [from Madison Keys]. The pace that Iga Swiatek hit that one out, Keys couldn't afford a big swing and it just flew off her racquet down the line.

This match remains on a knife-edge. Madison Keys keeps it on serve with a backhand winner down the line.
She's inching ever closer.

Iga Swiatek stays on the front-foot but again rushes her returns and gifts two easy points.
She dials thing back though and gets Keys moving, hitting a deep forehand to move to 30-30.

Former Wimbledon champion on BBC 5 Live and BBC SoundsIga Swiatek is almost too fast for her own good, she's almost not balanced and rushes in and gets a little too close to the ball.

Madison Keys rolls her eyes after a net-call sends her forehand wide. She then tries something different with a drop shot but can only slice into the net.
40-0, can Swiatek hold to love? Ah, that won't help. Two unforced errors from Swiatek opens the door, but she manages to find her lines again next point.
New balls pleased.

Former Wimbledon champion on BBC 5 Live and BBC SoundsIga Swiatek is trying so desperately to find some rhythm and find some of those shots that she knows will win the point which is those forehands down the line to Madison Keys.

Fabulous tennis from Madison Keys who sneaks an advantage with a fine first serve and then has Iga Swiatek scampering after a forehand winner she'll never reach.

Sometimes that happens in a match, you come against a player who you don't match up all that well.
