Wednesday's second-round action at Roland Garros features a loaded bottom half of the draw, though the headline clash between eighth seed Alex de Minaur and Madrid semifinalist Alexander Blockx was cancelled after the Belgian withdrew with a sprained ankle sustained in practice. The spotlight shifts instead to a generational showdown between Joao Fonseca and Dino Prizmic, two 20-year-olds who lit up the clay swing, meeting in one of the most anticipated matchups of the round. The comeback kings also collide as Thanasi Kokkinakis, fresh from his epic five-set rally against Atmane, meets Pablo Carreno Busta, who stunned 12th seed Lehecka without facing a break point. Alexander Zverev faces a Paris Olympics rematch against Tomas Machac, Novak Djokovic continues his rust removal against Valentin Royer, and Casper Ruud's fitness comes under the spotlight after his heat-related collapse in a harrowing five-setter against Safiullin.
Update: Blockx withdraws with ankle injury, De Minaur receives walkover
Alexander Blockx's breakthrough Roland Garros campaign ended before his second-round match could begin. The Belgian, one of the breakout players of the clay swing who reached the Madrid semifinals as a qualifier and cruised past Coleman Wong in the first round here with 13 aces and just one break point faced, withdrew on Tuesday evening after spraining his right ankle during practice. "Unfortunately during today's practice I heard a snap in my ankle while I sprained it, which is why I had to withdraw from tomorrow's match that I was really looking forward to," Blockx wrote on social media. The 21-year-old reportedly caught his foot on the backcourt tarpaulin and will travel to Antwerp for further tests. Alex de Minaur advances to the third round via walkover, where he will face either Mariano Navone or 26th seed Jakub Mensik. The eight seed dispatched qualifier Toby Samuel in first round's straight sets but the routine nature of that win reveals little about his readiness for what comes next. De Minaur is a former Roland Garros quarterfinalist, but eight of his nine previous appearances ended in the second round or earlier. A semifinal run at the Hamburg 500 last week offered encouragement, though in six of his last eight tournaments he has failed to win back-to-back matches.
Kokkinakis and Carreno Busta meet in battle of the comebacks
Two of Monday's most compelling first-round stories collide in a second-round matchup that neither player could have scripted. Thanasi Kokkinakis, who produced the comeback of the tournament so far by rallying from 4-1 down in the fifth set to beat Terence Atmane in a four-hour epic, faces Pablo Carreno Busta, who rolled back the years with a masterclass straight-sets demolition of 12th seed Jiri Lehecka without facing a single break point. Both are veterans rebuilding after extended injury absences - Kokkinakis returning from major pectoral surgery that kept him out for 11 months, Carreno Busta fighting his way back from the injuries that derailed his career in 2023. The Australian has won all four competitive matches he has played since his comeback but the physical toll of Monday's marathon is the obvious concern, particularly after he had played just three hours and 26 minutes of competitive tennis in the four months prior to Roland Garros. Carreno Busta, 34, looked rejuvenated against Lehecka with 10 aces and razor-sharp returning, but this was only his second clay-court win in an ATP main draw all season. Their first career meeting promises a fascinating contrast - Kokkinakis' raw power and serve against Carreno Busta's tactical precision and experience.
Zverev faces Machac rematch on familiar ground
Alexander Zverev returns to the scene of his Olympic triumph to face Tomas Machac in a rematch of their 2024 Paris Games encounter, which the German won 6-3, 7-5. The second seed looked every bit the title contender in his clinical straight-sets dismissal of Benjamin Bonzi on Sunday, winning 11 of 14 serve pressure points in a performance that underlined why he has reached at least the quarterfinals in each of the past five editions. Machac, returning from illness that forced his withdrawal from Rome after a first-round win over Stefanos Tsitsipas, beat Zizou Bergs in straight sets but arrives with question marks over both his health and consistency - the Czech has won just one tournament this season, the Adelaide 250 in January, and has failed to string back-to-back wins in all but one event since. Once ranked inside the top 20, Machac has slipped after failing to defend his Acapulco 500 title in March. Zverev's power, court coverage and big-match pedigree should see him through comfortably, though the Czech's ball-striking ability on his day means a slow start could prove costly.
Djokovic continues rust removal against another French opponent
Novak Djokovic faces a second consecutive Frenchman as he continues to shake off rust following a two-month shoulder injury layoff. The 24-time Grand Slam champion found his rhythm after dropping the opening set against big-serving Giovanni Mpetshi Perricard on Sunday, eventually winning in four sets with 45 winners against just 18 unforced errors. Valentin Royer, ranked 74th, represents a different challenge - the 24-year-old is primarily a Challenger circuit player who collected his first career Roland Garros main draw win and his only ATP-level clay court victory by beating qualifier Hugo Dellien in straight sets. He reached a Challenger final in Oeiras on clay in April, suggesting some comfort on the surface, but his 0-3 record against top-10 opponents leaves little doubt about the gulf in class. Djokovic will be expected to advance without significant difficulty, using this as another step toward match sharpness ahead of the tournament's deeper rounds where sterner tests await.
Fonseca and Prizmic set up generational showdown
One of the most eagerly anticipated second-round matchups pairs two 20-year-olds who have emerged as breakout stars of the clay swing. Joao Fonseca, the 28th seed and first Brazilian man seeded at Roland Garros since Thomaz Bellucci in 2011, overcame a nervy opener against qualifier Luka Pavlovic, saving a set point in the first-set tiebreak before pulling away for a straight-sets win. "I started the game with one level, and then I ended the game with another level," the world No. 30 said, a Monte Carlo quarterfinalist last month who arrived in Paris to another carnival atmosphere from Brazilian supporters. Dino Prizmic brings an even more compelling story - the Croatian swept past qualifier Michael Zhang 6-1, 6-1, 6-3 and arrives with a 35-10 clay record over the past 12 months across all levels, including a run to the round of 16 in Rome where he defeated Novak Djokovic along the way. Prizmic has made the transition from Challenger dominance - eight titles on all surfaces this year - to ATP contention, though his 3-7 record against top-50 opponents suggests that Fonseca's superior big-match experience could prove decisive. Their first career meeting promises to be one of the matches of the round.
Ruud faces fitness test against surging Medjedovic
The question hanging over Casper Ruud heading into the second round is not about form but fitness. The 15th seed survived an extraordinary first-round ordeal against Roman Safiullin, squandering five match points and suffering a heat-related collapse before somehow finding a way through in five sets. He lost 11 consecutive games at one point and was visibly struggling to move in the fourth set before producing a remarkable recovery in the decider. Hamad Medjedovic may not be a household name at 58th in the rankings, but the 22-year-old Serb's clay form this season has been quietly outstanding - 14-3 on the surface in 2026 with a Barcelona semifinal, a round of 16 run in Rome, and a first-round win over Yannick Hanfmann here that featured 13 aces and 83% first-serve accuracy. With the heat expected to persist and both players having been pushed physically in their openers, conditioning could be the decisive factor. Ruud has reached two Roland Garros finals and possesses the superior clay pedigree, but if Monday's exertions have left a mark, Medjedovic has the weapons and the form to capitalise.
Seeds expected to advance without drama
Andrey Rublev and Rafael Jodar should all progress comfortably through their second-round assignments. Rublev, the 11th seed who needed four sets to fend off Hamburg champion Ignacio Buse, faces Camilo Ugo Carabelli, a solid clay courter ranked 59th who reached the Hamburg quarterfinals last week but has managed just two Roland Garros wins across his entire career. Jodar continues his charge through an increasingly open quarter against James Duckworth, the Australian journeyman whose opponent Gabriel Diallo retired while Duckworth led 6-3, 4-1 - only his second win in 10 Roland Garros main draw matches.
