David Robertson
The oldest and longest-tenured member on this list, Robertson struggled in the second half of last year but bounced back in a big way with the 2024 Rangers. The 39-year-old has 67 appearances under his belt this year, posting a 3.04 ERA, even more impressive 2.63 FIP and a 130 ERA+ to go along with it.
He's no longer the shutdown closer that he once was on the Yankees, but that could work out well for the Blue Jays, who already have Jordan Romano and Chad Green on hand as potential closers on any given night.
Robertson, a 16-year veteran, is certainly at the end of his career, but as of right now he hasn't announced that 2024 will be his last. He's continued to show that he can defy Father Time and since he's already up there in age, he shouldn't break the bank for the Blue Jays. He's not going to be the answer to all their problems, but he'll give them a cheap, talented veteran who can easily be a leader in this clubhouse.
