Dennis Novak vs Christoph Negritu

Dennis Novak would likely be the favorite in this matchup, given his experience and consistency on the ATP Tour. He is accustomed to the rigors of high-level competition, and his steady game would likely be tough for Negritu to break down, especially if Negritu hasn't yet gained the experience needed to perform well against players with Novak's skill set.

Christoph Negritu might be the underdog here, and while he could have moments of brilliance, Novak’s solid and reliable baseline game would likely be too much for a player who is still developing. Negritu would need to play aggressively and take some risks to have a chance, but if he can't manage Novak’s consistency, it could be a difficult match for him.

In summary, Dennis Novak is the more established player and the favorite in this match. However, depending on Negritu’s form and his ability to play at a high level, he could still cause problems for Novak.
