With Oakland’s No. 1 (John Jaso), No. 2 (Derek Norris) and No. 4 (Luke Montz) catchers all on the shelf, the A’s needed to find someone to share time with Stephen Vogt. Suzuki makes perfect sense as a stopgap, even though he’s hit just .223/.284/.311 in 251 at-bats for the Nationals this year. He spent six years with the A’s until being dealt last August, and he’s familiar with several of their pitchers.
