Casper Ruud is currently competing in the 2022 ATP Korea Open, where he got past Nicolas Jarry in his opening-round match. K-pop superstar Kim Seok-jin was in the stands to watch the Norwegian in action, much to the delight of boy band BTS' fans around the world.Despite dropping the second set, Ruud got past the Chilean 6-2, 3-6, 6-3, but irked many of Jin's fans by stating that he didn't listen to the music of the world-famous band and was unaware that the singer was present to watch him.Jiniya_𝓨𝓸𝓾𝓻s 🌕@Jiniya1204<World renowned Idol group BTS #Jin's visit to the match made headlines.When asked if he knew BTS was watching his game,Ruud said "Didn't know.I don't actively listen to thier music but I know they're world-famous.

Casper got to do better win titles higher than ATP 250.Speaking ahead of the 2022 US Open final, Ruud asserted that the 750 points he won by virtue of his three 250 title wins had placed him within striking distance of the top spot in men's tennis."I'll hopefully take every match that I play seriously and know that every match is important," Ruud said. "That goes to show why I have the chance to become World No. 1, because I won three 250s this year which in the end gives me 750 points in the race. If I would have played those tournaments thinking, yeah, it's not that important because there's a Grand Slam coming, I wouldn't be in this position."The 23-year-old subsequently lost the US Open final to Carlos Alcaraz and currently occupies the No. 2 ranking.The Net magazine •@thenet_mWorld No. 2, Casper Ruud is the third player to qualify for Nitto ATP Finals.
