Derek Norris was in the A's original starting lineup Monday, which was expected because the Rangers were starting a left-handed pitcher, Ryan Feierabend.
But the A's other man in the 2014 catching platoon, the left-handed John Jaso, wound up getting the call behind the plate.
Jaso missed the last two months of the 2013 season because of concussions, and manager Bob Melvin had to balance three catchers — Norris, Stephen Vogt and Kurt Suzuki the rest of the way, a move that was largely successful.
Now the A's are basically down to two catchers, Norris and Jaso, with Vogt being deemed expendable because he has options, which means he can be sent to Triple-A Sacramento while the other two can't be.
And Melvin needs to know that Jaso can be counted on to for a large part of the grind starting opening day.
