The fresh pickleball vs tennis debate is far from its end as Andy Roddick recently took a fresh dig at the sport amid his online spat with a young tennis pro-turned-pickleball player named Christian Alshon.Roddick no longer competes on the tennis courts but his love for the sport hasn't died. He quit the sport professionally in 2012 but his post-retirement life has revolved around tennis majorly since then. He currently covers the sport as an announcer, an analyst, and a podcaster.Furthermore, Roddick hasn't shied away from voicing his opinions online, especially on tennis-centric issues. A couple of days ago, he joined the likes of James Blake and Nick Kyrgios in opposing Christian Alshon's view that pickleball created superior athletes."Pickleball has made me a much better athlete than Tennis ever did. Point for point, pickleball requires more skill than tennis," Alshon wrote on X (formerly Twitter).Roddick labeled Alshon's opinion dumb, writing:"If anyone pickle person ever ranks higher in tennis than what Sock will be at end of this year in his new paid pickle hobby, I'll commentate a pickle match standing on my head. This ain't a real discussion. Fun game. Dumb conversation."Alshon for the most part debated with James Blake but Roddick chimed in at several instances. He eventually exited the conversation writing:"He's had his attention. Now I just want to get kicked out of this conversation like he got kicked out of Virginia. Pickle is fun, and I understand how all this is good for it. It does nothing for us. I'm out."Alshon, however, didn't let Andy Roddick slide and took a dig at his podcast."You're the one that responded to me first. This is more engagement than your podcast gets in a year, I believe that does something for you," the youngster tweeted.A couple of days later, the former US Open champ reignited the row. He took to X and shared a video of a traceur doing parkour. Roddick sarcastically called the activity "less athletic" than pickleball, saying:"Another thing that's less athletic than pickleball ……. How would this guy be able to keep himself out of a kitchen during all the dinking? That takes real athleticism."Christian Alshon challenged Andy Roddick for a pickleball showdownAndy RoddickDuring the heated exchange, Christian Alshon bet $300,000 in total for pickleball duels with Andy Roddick, James Blake, and Nick Kyrigios."@NickKyrgios @JRBlake @andyroddick how about this. I challenge you three to back to back singles matches for 100K each. I’ll give you 2/1 odds which in your minds should be crazy good odds. You have 6 months to train," Alshon wrote.An X user suggested that Alshon's challenge felt like a knockout blow to Roddick in a way similar to his losses to Roger Federer on the tennis court."Christian owned you on Twitter like Federer owned you at life," the user wrote.The American then ridiculed Alshon's short-lived tennis career in his reply to the user."Yeah. He’s totally like Roger. If Roger had D-2 titles in his Twitter bio and played pickleball," Andy Roddick wrote.For context, Andy Roddick played against Roger Federer 24 times between 2001 and 2012 and could collect only three wins.
