Open Extended Reactions
Welcome to ESPN India's daily blog, where we aim to bring you all the news from the dynamic world of Indian sports: from the wide variety of Olympic sports to franchise leagues.
May has plenty of sporting action taking place - which you can find listed out in ESPN India's sporting calendar.
All four Indian boxers progress at Olympic qualifiers
India's Sachin Siwach (57kg), Sanjeet Kumar (92kg), Amit Panghal (51kg) and Jaismine (women's 57kg) inched closer to a quota for the Paris Olympics as each of them registered wins at the Boxing World Qualifiers in Bangkok today.
Sachin set the tone with a clinical 5-0 win over Turkey's Batuhan Ciftci in the pre-quarterfinal round and then Sanjeet defeated Luis Sanchez of Venezuela with an identical margin in the round of 32. Sachin needs to win two more bouts to make the cut for the Paris Games as only three boxers win quotas in the 57kg division, while Sanjeet, who got a bye in the previous round, will have a similar target as all four semi-finalists will qualify in his weight category.
Later in the day, Jaismine got the better of Azerbaijan's Mahsati Hamzayeva to progress in the women's 57kg with a 5-0 verdict. Amit Panghal, former world championship silver medallist, completed a perfect day for the Indian contingent as he got the better of Mexico's Mauricio Ruiz 4-1.
Treesa-Gayatri upset World No. 2 Baek-Lee
Treesa Jolly and Gayatri Gopichand stunned the world No 2 pair of Baek Ha Na and Lee So Hee 21-9, 14-21, 21-15 to enter the quarterfinals of women's doubles at the ongoing Singapore Open Super 750.
This was the one positive spot for India after the tough three-game losses suffered by Sindhu and Prannoy (more on that below)
Treesa and Gayatri have going through a rough patch on the BWF Tour and falling down the rankings to world No 30, but on Thursday rode the momentum to get a big win after a long time. Indeed this was their first win from three meetings against the South Korean pair.
The Baek-Lee duo was error prone to start with as Treesa and Gayatri held a commanding 18-9 lead before taking the opening game with relative ease. But the Indians the South Koreans bounced back and the Indians' unforced errors count meant they had to play a decider.
The third game was close, locked 8-all before the Indian duo took a slender two-point lead at the final mid game break. They continued to play with aggression and reeled off six points on succession to make it 16-9 and seal a memorable win.
Next up, they face another Korean pair in sixth seeds Kim So Yeong and Kong Hee Yong, who they had lost to at the Hangzhou Asian Games last year in their only meeting so far.
Sindhu loses to Marin
In the Singapore Open round-of-16, PV Sindhu lost to Carolina Marin after a marathon match which ended 13-21, 21-11, 22-20 in the Spaniard's favour; Sindhu's wait for defeating her long-term rival continuing through a sixth year.
Here is how the match progressed game-by-game:
Sindhu takes first game 21-13
Marin started the stronger, but Sindhu grew into the game, pulling back a early 1-3 deficit to lead 7-4. Marin narrowed that to 7-6, but a combination of a superb overhead crosscourt smash and stubborn defense saw the Indian pull away to a 11-6 break at the interval. Marin closed it to 11-8, but tat was as close as she got, as she took over completely, racing away to take it 21-13
Marin takes second game 21-11 to force decider
Marin started the second game in much better form, finding the angles and hugging the wide lines, sprinting to a 4-0 lead. That became 6-1 before a sensational crosscourt smash from Sindhu arrested momentum, temporarily. Marin's lead reduced slightly to 8-4 before she stepped on the gas again to take the lead at the interval of the second game, 11-6. A controlled clear and kill smash made the first point after that Sindhu's but a misjudgement of a long Marin clear meant any potential momentum building was stalled as Marin took a 13-7 lead. Marin then stepped on the gas as she raced to a 17-7 lead, eventually taking the game 21-11.
Marin takes the third game 22-20, and the match 2-1.
Impeccable defence from Sindhu saw her race into an early lead in the third, 3-0 after forcing errors off Marin. The Spaniard won her first point immediately after that, though, with a delicate disguised drop that left Sindhu completely flat-footed. A body smash made it 3-2, but Sindhu again made the most of a couple of errors to take the lead to 5-2 and then two superb drops made it 7-2, Sindhu's intensity throwing Marin off and nullifying the momentum the Spaniard had built through the second game. Marin's controlled aggression, though, brought her right back into the game drawing the scores close to 8-6 and then 9-8 and 10-9 before a sensational horseshoe drop made it 11-9 at the interval. She stretched the lead out to 15-10 with a combination of aggressive shot-making and Marin over-playing her hand on occasion. Errors from Sindhu, pretty basic ones, then got Marin back in the match, 15-13, before Sindhu pulled out again to a 17-14 lead. The game by now had descended into a war of attrition, both champion athletes making errors at vital moments, and another straightforward smash into the net from Marin saw Sindhu maintain a three-point advantage at 18-15. A forceful push that was misjudged by Sindhu, though, made it 18-17 before a long clear saw the score tick over to 19-17 but a Sindhu error and a Marin body smash saw the score tied at 19-19. Another error and at 19-20, Marin had a match point which she squandered with a wild smash wide. Superb transition from defence to attack saw Marin smash her way to another match point, which she won after another terrible misjudgement of a simple long clear: in many ways symbolic of the errors that cost the Indian this game.
HS Prannoy loses to Kenta Nishimoto
In a long three-gamer, Japan's Kenta Nishimoto bested India's top men's singles player, HS Prannoy, 21-13, 14-21, 21-15. It will be a concern that Prannoy continues to struggle for form after health issues kept him out of action for a month, with the Paris Olympics drawing closer.
Praggnanandhaa beats Carlsen
Rameshbabu Praggnanandhaa has beaten 5-time World Champion Magnus Carlsen in the classical chess format for the first time. He took down the world no.1 with white pieces in the third round of Norway Chess 2024, taking an advantage out of the opening and converting it calmly. With the win the young Indian takes sole lead of the event, with 5.5 points.
Praggnanandhaa, traditionally a stronger player in the quicker formats of the game, has been focussing on classical chess over the past year, and his improvement in the format has been marked. Earlier this year, he'd competed in the Candidates 2024, competing against the best in the world (excluding Carlsen - who opted out) as they competed to win the honour of challenging the world champion, Ding Liren. He finished fourth there, but took away important lessons: 'If I was more practical, I'd have been better'. This win now, against one of the greatest players of all time, is his biggest in the format and marks further progress.
Praggnanandhaa is now half a point clear of USA's Fabiano Caruana who scored his first victory in classical against reigning world champion Ding Liren of China. Carlsen, on three points, looks like a distant third for now in the updated standings but with each classical win worth three points, this might not hold for too long.
Hikaru Nakamura of United States, Firouzja Alireza of France and Liren are all joint fourth currently on 2.5 points in the six-player double round-robin contest. "I wish Magnus would take similar risks against us old folks," said Nakamura on Carlsen's choice of playing a risky battle against Praggnanandhaa.
Vaishali inched up to 5.5 points too and enjoys a full-point lead over women's world champion Wenjun Ju of China who is sole second by a half point margin over compatriot Tingjie Lei.
Muzychuk, Pia Cramling of Sweden and Koneru Humpy share the fourth spot here on three points each.
