Just about the time you memorize the roster of the Seattle Mariners spring roster, they change it.

For the second time in as many days, the Mariners made a player move, inviting journeyman catcher Jason Phillips to camp.

Why?

The Mariners are short-handed with catchers because Kenji Johjima is in Japan training for the World Baseball Classic, and Luis Oliveros is out with a torn anterior cruciate ligament in his left knee.

That left four healthy catchers - Jeff Clement, Rob Johnson, Adam Moore and Jamie Burke - to catch the 30 pitchers in camp.

Now, there will be five.

Phillips, 32, has spent parts of seven seasons in the big leagues, playing for the Mets, Dodgers and Blue Jays.

Barring a train wreck involving all the catchers ahead of him on the depth chart, Phillips won't make the team. Consider him insurance and an immediate glove to help handle the pitching here in Peoria.
