One of the things about having a more established team is there are fewer spring training roster battles. Backup catcher isn’t exactly the most glamorous position, especially when backing up one of the league’s more famous iron men, but it is one of the things we have to watch this spring alongside the yearly bullpen battle and the platoon obstacle course in right field. As a reminder, the candidates are:

  • Andrew Knizner. Knizner has the advantage of being on the 40-man roster and earning actual guaranteed money no matter what happens this spring. He also has the backing of our own Connor Donovan, who came away from writing Knizner’s 40 in 40 with a newfound appreciation for the career backup.
  • Jhonny Pereda. Pereda has the advantage of being on the 40-man roster, although he did not inspire the same strong feelings in ZAM that Knizner did in Connor. Pereda’s other advantage is he has an option year left.
  • Mitch Garver. After saying earlier this winter that the team hadn’t had any conversations about bringing Garver back, Cal Raleigh apparently influenced the organization to bring back Garver on an MiLB deal after he went unsigned this winter. Garver has the advantage of knowing the system and the way he fits on this roster; he’s also enjoyed the most successful career out of any of the potential candidates, as a World Series champ with a Silver Slugger.

Then there are the non-roster invites currently in camp with the Mariners. Two are MiLB journeyman who have been with the Mariners in the past in Bryan O’Keefe and Nick Raposo, and three are homegrown prospects Josh Caron, Connor Charping, and Luke Stevenson. Jakson Reetz, another MiLB journeyman, rounds out this group. This crew is here mostly to catch because catchers make the spring training world go round – and gain experience in the case of the prospects – but there’s an outside outside outside chance O’Keefe, Raposo, or Reetz might have a late-career resurgence. Realistically, though, this is a three-horse race between Knizner, Pereda, and Garver. Given those options, which of the the three is your early spring pick to make the Opening Day roster? Really, what this question asks is: what do you see as the role of a backup catcher, and what traits do you value most in that position?
