Temba Bavuma Drops Bomb, Says Australia Used 'Choke' Word While Sledging South Africa In WTC Final
The Australian cricket team has traditionally been a part of several controversies purely because of their repeated acts that crossed the line while sledging the opponent team's players. Though the modern team, led by Pat Cummins, has been touted to be much different, even this side crossed a line during the World Test Championship final against South Africa. Seeing the Proteas inching closer to a victory on Day 4 of the WTC final at Lord's, the Australians are said to have used the dreaded word 'choke' in order to unnerve Temba Bavuma and his men. Australia seemed to have attempted to use all the tricks in their hat in order to disturb the Temba Bavuma- Aiden Markram partnership. During a chat after helping South Africa seal the WTC final, Bavuma said he could hear words like 'choke' while batting in the middle. "While we were batting, we could hear the Aussies using that dreaded word: choke," said Bavuma on BBC Test Match Special. "We came in with a lot of belief and a lot of doubters. We got ourselves into the final, and there were doubters as to the route we took. This win squashes that. Here's an opportunity for us as a nation, divided as we are, to unite." "As a country, it's a chance for us to rejoice in something, to forget about our issues and really come together. I hope it inspires and continues to inspire our country. For this group of players, there were a lot of doubters but the way we played would have wiped all of that out," the South Africa skipper added. Proteas spinner Keshav Maharaj also spoke on the 'chokers' tag that South Africa have had to live with for a long time. He is hoping the word would now be history. "It'll be great not to have to hear that again. To have got the job done and to get rid of that is quite a big thing for this team. All the questions that have been asked in the past have now been answered," concluded the sole centurion of the match. Australia skipper Pat Cummins, on the other hand, said that there could be the need of a 'change' as his team looks to bounce back. "We've obviously got a team here that got us to the final so it's about when do we feel it's the right time to change," Cummins, said. "After this Test match, everyone is thrown back into the conversation so it's a bit of a reset. It's probably more for me and the selectors to sit down and map it out."

Kambosos Jnr suffers devastating world title loss
George Kambosos Jr's distinguished career may be over following a comprehensive world-title loss in New York to classy American Richardson Hitchins. With surgical precision, Hitchins dominated from the get-go before stopping Kambosos two minutes 33 seconds into the eighth round with a second devastating body shot at Madison Square Garden had been bidding to join the great Jeff Fenech as a multi-division world champion but instead copped a pounding in Sunday's much-anticipated IBF super-lightweight showdown. Having promised to put Kambosos in his place after an explosive build-up spiced with threats, bets and a cancelled face-off after the two combatants almost came to blows, Hitchins delivered on his rap-dancing his way into the ring, the undefeated New Yorker showed Kambosos little respect once inside it and when it became patently obvious he had the Australian's measure. Enjoying a significant height and reach advantage, the so-called "Pride of Brooklyn" kept an aggressive Kambosos at bay in the opening round, then won the second after opening up a cut under the challenger's right eye. Hitchins continued to pepper Kambosos with jabs, much like in the Sydney slugger's twin defeats to Devin Haney, to win all seven rounds before gesturing to the former unified lightweight world champion's camp to throw in the towel. They didn't, leaving the referee with no choice but to stop the contest when Kambosos was left reeling in pain following a huge blow to the solar plexus. After stripping fellow Australian Liam Paro of his IBF belt last December in Puerto Rico, Hitchins has now placed Kambosos's career in tatters. The 32-year-old has now lost four of his past six bouts and conceded after his latest defeat that all he wants to do next is coaching his son's football team.

The hard questions needed to be asked about Super Rugby
There was some outstanding rugby played throughout Super Rugby, with tournament organisers justified in talking up the increased competitiveness of games and uptempo rugby. But there are hard questions to be asked of the competition based on the following: in the four years since its inception, only three teams have made the Super Rugby Pacific grand final (Crusaders, Chiefs and Blues). Further, in the 12 semi-finals and grand finals in the 2022-2025 period, only one game involved a team that wasn't the Crusaders, Chiefs, Blues or Brumbies. This is atypical of not just comparable tournaments around the world, but of Super Rugby itself, especially in the 2011-2016 period that produced a diversity of finalists and winners. Competition owners Rugby Australia and New Zealand Rugby should be asking themselves three things: what changed (or didn't change) after the end of the 'old' Super Rugby to create this four-team dominance?; will it change in the coming years? (in my opinion, no); and if not, what are they going to do about it? Lolesio loss really hurt the Brumbies The Brumbies gave it a crack against the Chiefs in Hamilton on Saturday, although even the most committed Brumbies' fans must have had a sinking feeling when James Slipper was penalised just before halftime, an area where the Brumbies had to dominate if they wanted to cause an upset on the road. However, the key moment of the game was the loss of Noah Lolesio in the early stages due to a failed HIA. Not surprisingly, it took Jack Debreczeni about 15-20 minutes to find the rhythm of the game, and even when he settled he was always going to find it hard to replicate the influence that Lolesio has on the Brumbies' game. The Chiefs got a big bump from their bench - the replacement props maintained the scrum pressure while halfback Xavier Roe and playmaker Josh Jacomb were sharp. Combustible Cheika may be too hot to handle Michael Cheika almost went out in a blaze of glory with Leicester at the weekend, narrowly losing the Premiership final 23-21 to Bath, but he had one last spray for match officials. Calling a yellow card to prop Dan Cole 'embarrassing for the game', Cheika was also critical of how the scrums were officiated and was clearly irate on the sidelines. It's all part of the package with Cheika, who has an amazing record of turning teams around but also comes with obvious baggage. Wallabies legend Tim Horan this week called for Australian rugby to find a role for Cheika somewhere in the system but there is no mystery while administrators at national or state level don't seem to be rolling out the red carpet. He's an enormous character, obviously very smart but complex, and not the coach for any chief executive who already has enough on his or her plate. New Super Rugby AU competition will be a step forward There appears to be a diminished appetite in New Zealand for Australian players, which is just one more reason why the much-expected Super Rugby AU competition in September would be a good thing. It's thought to be one round and a final, and therefore quite limited in scope, but it will still plug a gap in the calendar for those players who aren't involved in the Wallabies. Everyone is struggling with the 'third-tier' format - debates in New Zealand and South Africa are fairly constant about the role of the NPC and Currie Cup, respectively, but the consensus remains that although the perfect model is elusive, an imperfect competition is preferable to the void that Australia has been a constraint on Australian rugby for years.
