Kecmanovic v Evans
It's almost time for Dan Evans to begin his French Open campaign.
The British number one will be aiming to continue his fine form in 2021 as he takes on Serbia's Miomir Kecmanovic over on court six.
Paula Badosa has just beaten Lauren Davis, so they'll be on shortly.
Tig 4-6 6-6 Osaka
First point to Osaka, before she half-heartedly bangs a return into the net. 1-1.
A brazen serve from Tig then lands a fraction out, she goes to check it with the chair umpire. She gets the next point but scuppers the one after, flopping a backhand between the tramlines.
Tig* 2-3 Osaka in the tie-break.
Tig 4-6 6-6 Osaka
A lovely, controlled winner from Naomi Osaka off a spinning drop shot from Patricia Maria Tig kicks this game off, but Tig levels.
More brilliant exchanges between the two bring up 30-30, before a magnificent forehand across court from Osaka takes us to deuce.
Osaka then gets her first match point. Can she capitalise? Nope. Epic play from Tig with a bold forehand down the line.
A ROAR from the Romanian as she gets the advantage next, some really great work from her. Until, that is, she sends a forehand into the tramlines. Hands on hips.
She gets it the next time with a lovely lob. Tie-break time.
Kalinina 6-2 6-4 Kerber
A Grand Slam remains elusive for 26th seed Angelique Kerber. The three-time Grand Slam champion has been beaten by world number 139 Anhelina Kalinina 6-2 6-4.
Ukraine's Kalinina had never made it past qualifying until now. Now she takes out a former world number one.
Kerber, 33, has reached the quarter-finals here twice, but this is the German's third successive exit in the first round.

Naomi Osaka handles some tricky play expertly to battle through to 40-0. An easy love-hold and the pressure returns to the shoulders of Patricia Maria Tig.
Tig 4-6 5-5 Osaka*
Patricia Maria Tig is serving to stay in the game. After a shaky start, she pulls it back to 40-15. Osaka's not happy as she marches back to the baseline, after she slams a backhand into the net from metres out when she really should have capitalised on that opportunity.
Tig holds on the next point.

At 30-30, she asserts her dominance with a nicely-placed backhand winner, sliding in towards the net.
She goes long on the next point though and looks a tad frustrated as we move to deuce. A shake of the head from Tig as she messes up a return from an inviting serve, and Osaka goes on to hold.

Elsewhere at Roland Garros, three-time Grand Slam champion Angelique Kerber is in a spot of bother early on as Ukrainian world number 139 Anhelina Kalinina takes the first set 6-2.
