Jeff chats with guest Erik Jonsson (@erktennis), of Tennisportalen and Sourcepodden, about last week's ATP NextGen Finals, which included up-and-coming Swedish star Mikael Ymer. We talk about the stunning rise of Jannik Sinner, the progress shown by Alex De Minaur, and we consider the advantages and disadvantages of a whole slew of the rule innovations that are employed at the NextGen event in Milan. We also delve into Mikael Ymer's potential, whether older brother Elias could still become a top-100 player, and if there is any reason why so many prominent umpires hail from Sweden. Finally, we chat about Erik's Tennis Hipster Handbook, and we wonder whether it's possible to follow tennis anymore without Twitter.
