In the match between Fabio Fognini and Casper Ruud, I am confident that Ruud will win without any major problems. Fognini has not been showing a high level of play for a long time, has inconsistent performances, and often makes errors. Meanwhile, Ruud is in excellent form, has made significant progress in recent years, and is an experienced player. Additionally, Ruud's ranking is significantly higher, indicating that he is motivated for a successful performance in the tournament. Therefore, Fognini's chances of winning are extremely low, with Ruud having a decisive advantage.
