The Blue Jays showed at least preliminary interest in the 3 top RPs to sign so far (Iglesias, Maton and Helsley). They remain interested in adding a 7th to 9th inning arm.
Given how Ross Atkins' front office is known for casting a wide berth in its free agent explorations, it's probably safe to guess that the Jays have called about most or all of the top relievers on the market, ranging from set-up men to proven closers like Diaz.
Atkins said after the season that the team was open to the possibility of moving Jeff Hoffman into a set-up role, thus opening the door for Toronto to seek out another top saves candidate.
