The Jamaican winger, who played with Richard King at Cavalier, has joined his countryman in Paisley after he put pen to paper on a two-year deal.
The welcome mat has been rolled out at St Mirren for Jalmaro Calvin as he became the club’s ninth summer signing.
The Jamaican international is reunited with team-mate Richard King just weeks after he departed the island’s Premier League outfit Cavalier.
The pacy winger has penned a two-year deal at the SMiSA Stadium with the club holding an option to extend terms for a further year.
While at the Kingston-based club, Calvin notched 39 goals in 101 appearances and also featured in the Concacaf Champions Cup.
Saints boss Stephen Robinson insists Calvin was someone that always caught the club’s eye every time they were scouting King.
He said: “Jalmaro was a player that kept coming up every time we looked at Richard. We’ve built up a really good relationship with Cavalier and their owner Rudolph Speid.
“Jalmaro has real pace and energy. He can play wide and he can play through the middle.”
The Northern Irishman has outlined his vision for Calvin while comparing him to a former Saints favourite.
He added: “We need to build him up. He’s a project for us in terms of getting him used to the Scottish game and the physicality but his electric pace will give us something that we don’t have in the squad at this time. He reminds me of Toyosi Olusanya in terms of that raw pace that he can offer us in the wide areas.”
Calvin’s capture is the latest addition and follows Ryan Mullen, Liam Donnelly, Jayden Richardson, Richard King, Tunmise Sobowale and Malik Dijksteel signing on.
Killian Phillips and Roland Idowu turned loan deals from Crystal Palace and Shrewsbury Town, respectively, into permanent moves.
Jalmaro will wear the number 17 shirt this season while fellow new signing Sobowale has been assigned number 19.
And it doesn’t look like business is done for Saints with former Livingston and current Wycombe Wanderers keeper Shamal George a target.
The 27-year-old custodian has only made five appearances for the Chairboys since joining in August 2024 and may be brought in to challenge Peter Urminsky and Mullen for the No 1 jersey.
