22:28 CET - Jannik Sinner is into the French Open final! Novak Djokovic put up one incredible fight, but the Italian world number one got the better of the Serbian with a fine display, winning the three-hour battle 6-4, 7-5, 7-6(3). It's his 20th successive win at a grand slam and he will now face Carlos Alcaraz on Sunday in a final not to be missed.
21:10 CET - A gruelling second set of tennis has gone the way of the world number one Jannik Sinner after 71 minutes. The Italian was broken for the first time since the first round of the tournament by Novak Djokovic, but he found his way back to win it 7-5 and put one foot in the final.
19:58 CET - It is advantage Jannik Sinner at Roland Garros, with the Italian world No. 1 taking the opening set 6-4 against Novak Djokovic. Despite a bit of a wobble in the middle, Sinner looked to be in control, and his Serbian opponent will need to find a way to turn this around.
19:02 CET - We are just minutes away from the second French Open semi-final of the day between world No. 1 Jannik Sinner and 24-time Grand Slam champion Novak Djokovic. Both players are now taking to the court, and it promises to be an absolute thriller!
17:07 CET - Defending champion Carlos Alcaraz is back into the French Open final after Lorenzo Musetti retired from their semi-final, trailing 6-4, 6-7(3), 6-0, 2-0. The Italian appeared to be struggling with a thigh injury towards the end, and is unable to continue. His fine clay-court season comes to a disappointing close.
Meanwhile, Alcaraz now stands on the verge of a fifth Grand Slam title and his second here, but he will certainly have to be better against either Jannik Sinner or Novak Djokovic in the final. The Spaniard was well off his best in the first two sets, playing inpatience tennis and making several errors. However, he has two days to get ready, and you can be sure he will be.
16:58 CET - Carlos Alcaraz has found top gear now, and has soared ahead to take the third set 6-0 against a Lorenzo Musetti who appears to be tiring. The Spaniard is fully in the driving seat now.
16:34 CET - It hasn't been vintage stuff at all from Carlos Alcaraz at Roland Garros, and he is making plenty of errors, but he has still managed to find a way to snatch the second set 7-6(3), and level proceedings against Lorenzo Musetti. When it really mattered, the Spaniard upped his game in the tiebreak, against an opponent who is playing extremely well.
15:29 CET - Well, hello there! Lorenzo Musetti has broken in the final game of the set to take the opener 6-4 against Carlos Alcaraz. A solid set for the Italian to win it, with a solid serve and good play at the net.
14:34 CET - Carlos Alcaraz and Lorenzo Musetti are out on the court warming up, with the start of the first semi-final just minutes away.
12:00 CET - Welcome back to the Tennis Tracker this Friday afternoon, with a pair of seismic semi-final clashes on the cards at the French Open.
Up first at 14:30 CET, defending champion Carlos Alcaraz takes on Lorenzo Musetti, who has enjoyed a stunning clay-court season, reaching at least the semi-finals at every event.
Alcaraz will definitely go into the match as the favourite and has beaten Musetti on the clay of Monte Carlo and Rome in the last few months. He also leads the head-to-head 5-1. However, the Italian is playing the best tennis of his career and will be targeting an upset.
That will be followed by a massive meeting between world number one Jannik Sinner and three-time French Open champion Novak Djokovic.
For the first time in a while, Djokovic goes in as the big underdog. He has done a remarkable job getting to the semi-finals at 38 years old and with not much form this season, but will this be a step too far? However, write off the legendary Serb at your peril, and he will certainly have a plan for Sinner.
Sinner has been utterly relentless this tournament, not yet dropping a set and swatting aside all his opponents with ease. But this will certainly be his biggest test, and if he is slightly off his best, Djokovic will do everything to make him pay.
