After withdrawing from the 2022 Wimbledon Championships (due to an abdominal injury) one day before his semifinal clash against Nick Kyrgios, Rafael Nadal is now gearing up for the US Open series. The Spaniard hasn't lost a single match at this year's Grand Slam tournaments, having won the Australian Open as well as Roland Garros.His sister Maribel Nadal recently took to social media to share a video in which the 36-year-old can be seen working hard on an indoor hard court at the Rafa Nadal Academy in Spain. The highlight of the video, however, is that the opponent is his uncle and former coach Toni Nadal's son Joan Nadal.Both men are seen hitting explosive forehands at each other, with the 22-time Grand Slam champion finally winning the point. Tennis fans had a few hilarious reactions to the short clip, commending Nadal for his fine movement but also expressing a soft spot for his cousin."Guy is even using those small grunts, he wants to destroy his cousin and make him never play tennis again lmao," a user wrote.Hicham Gherbi@gherbi_hichamGuy is even using those small grunts, he wants to destroy his cousin and make him never play tennis again lmao. twitter.com/rafastefbaes/s…mimi🧍🏻‍♀️| emotionally unstable era@rafastefbaesrafa not going easy on his 18 year old cousin 1143rafa not going easy on his 18 year old cousin 😅 https://t.co/gsbpzXrS7hGuy is even using those small grunts, he wants to destroy his cousin and make him never play tennis again lmao. twitter.com/rafastefbaes/s…"Knowing he hits harder at practice than real matches, his cousin is braver than the marines for volunteering," a fan tweeted.ash 🎯@lwtfinallyfreeknowing he hits harder at practice than real matches…his cousins braver than the marines for volunteering twitter.com/rafastefbaes/s…mimi🧍🏻‍♀️| emotionally unstable era@rafastefbaesrafa not going easy on his 18 year old cousin 743rafa not going easy on his 18 year old cousin 😅 https://t.co/gsbpzXrS7hknowing he hits harder at practice than real matches…his cousins braver than the marines for volunteering twitter.com/rafastefbaes/s…"Meet another Nadal: this time, young Joan, Uncle Toni's son, who looks as good as Rafa at the Academy," another fan said.Hélio Sassen Paz@heliopazConheçam outro Nadal: desta vez, o jovem Joan, filho do Tio Toni, que encara Rafa numa boa na Academy! twitter.com/ESPNtenis/stat…ESPN Tenis@ESPNtenis¿Nadal vs. Nadal? 🤔🤯 ¡Sí, claro! 🤩Rafa está ajustando los últimos detalles antes de partir a la gira norteamericana y, para ello, entrenó con Joan, el hijo del Tío Toni. mariabel_nadal/IG@rafaelnadal61935¿Nadal vs. Nadal? 🤔🤯 ¡Sí, claro! 🤩Rafa está ajustando los últimos detalles antes de partir a la gira norteamericana y, para ello, entrenó con Joan, el hijo del Tío Toni. 📹 mariabel_nadal/IG@rafaelnadal https://t.co/APISE145vuConheçam outro Nadal: desta vez, o jovem Joan, filho do Tio Toni, que encara Rafa numa boa na Academy! twitter.com/ESPNtenis/stat…"Just in this practice point alone Rafa's footwork is just so so good the way he's able to make those quick steps to get around to hit forehands it's great," a tweet read.Harrison@HaarriissonJust in this practice point alone Rafa's footwork is just so so good the way he's able to make those quick steps to get around to hit forehands it's great. twitter.com/rafastefbaes/s…mimi🧍🏻‍♀️| emotionally unstable era@rafastefbaesrafa not going easy on his 18 year old cousin 243rafa not going easy on his 18 year old cousin 😅 https://t.co/gsbpzXrS7hJust in this practice point alone Rafa's footwork is just so so good the way he's able to make those quick steps to get around to hit forehands it's great. twitter.com/rafastefbaes/s…Bored-.-Guy@BoredGuy0368925@rafastefbaes Cousin plays better than some of the top 200 players 27@rafastefbaes Cousin plays better than some of the top 200 players 😂Kushagra Bhardwaj@bharkushUncle Tony's son is in the making. #RafaelNadal twitter.com/rafastefbaes/s…mimi🧍🏻‍♀️| emotionally unstable era@rafastefbaesrafa not going easy on his 18 year old cousin 79343rafa not going easy on his 18 year old cousin 😅 https://t.co/gsbpzXrS7hUncle Tony's son is in the making. #RafaelNadal twitter.com/rafastefbaes/s…VamosRafa💞Siempre@iamladanth@gherbi_hicham His cousin only gets 1/100th of what his dad taught/tortured Rafa. ;p3@gherbi_hicham His cousin only gets 1/100th of what his dad taught/tortured Rafa. ;pTennis In the Park 🇺🇦@TennisInthePar1@rafastefbaes I suppose we should not compare to Rafa at 18.
