After Miami, where he reached the semis, Denis Shapovalov appears to have split with his previous coach, Rob Steckley.
The switch comes just as Shapovalov has broken into the top 20 in the rankings, despite a so-so start that saw him go 9-6 this season before Miami and fall 6-0 to Novak Djokovic in the fourth set of the Australian Open.
Shapovalov and Fuorivia are already in Monte Carlo, where the Canadian No. 2 will play next week at the ATP Masters 1000 tournament.
Fellow Canadian Fuorivia coached Shapovalov to the 2016 junior boys singles at Wimbledon.
Shapovalov begins his clay campaign with some momentum, and a little history of success on the surface.
In Miami, he defeated No. 8 Stefanos Tsitsipas to reach his first 1000-level semifinal before falling easily against the 20-time Grand Slam champion Roger Federer 6-2, 6-4.
In 2018, Shapovalov reached the semis of the Madrid Masters on clay, defeating Milos Raonic and Kyle Edmund before going down against Alexander Zverev.
