Medvedev, the former United States, came out of the top 10 after a difficult start for this season.
He has not won the title since Rome Master in 2023, which was also on Clay, and has not reached a final since Indian Wales last year.
Medvedev said often he does not like to play on clayand external After beating Jachnov, the crowd reminded: “It is the first match in Clay – it's not a favorite superficial.
“I don't think Karen hit one of the Ace and he is a big servant. Therefore, it was very slow, but I am happy with my inspiration in general and I look forward.”
Medvedev will face Alexander Muller from France in the second round.
Seventeen of the best 20 men's players will participate in Monte Carlo, including Novak Djokovic, Carlos Alcaraz and Jack Derbar from Britain.
