The Greek had already won in the Principality last year, so he does not win points.
On the other hand, in front of him, several big names lose some, starting with the Serbian Novak Djokovic, still N.1 in the world but eliminated prematurely last week in Monte-Carlo.
For Davidovich, only 22 years old, this 27th place in the world is the best of a career in which he has not yet won any title on the ATP circuit.
The other good deal of the week is for the Bulgarian Grigor Dimitrov, beaten in the semi-finals by the young Spaniard, who gains 6 places and moves up to 23rd place.
The Russian Daniil Medvedev, absent due to hernia, remains 2nd behind Djokovic, and the German Alexander Zverev, beaten in the semi-final on Saturday by Tsitsipas, logically retains his 3rd place.
Two other members of the Top 6 are injured, Rafael Nadal (4th) and Matteo Berrettini (6th).
The one and only change in the Top 20 is the reversal of places between the Argentinian Diego Schwartzman (15th), another victim of Tsitsipas in Monte-Carlo, in the quarter-finals, and the Canadian Denis Shapovalov (16th).
On the French side, Gaël Monfils remains 21st without having played in Monte-Carlo, due to a right foot injury.
His compatriots in the Top 100, eliminated in the first round, gain one or two places.
