Brantly, who joined the Mariners only about two weeks ago, could win the backup catcher job, though Steve Clevenger is still the favorite, the Tacoma News Tribune reports.

EDGE Analysis

Brantley joined the Mariners on March 12, but he has impressed with his play this spring. The Mariners traded Mark Trumbo and his contract for Clevenger, so it would be a little surprising if he doesn't win the job. Both players are out of options, but the Mariners likely will try to sneak one through waivers. Both are also left-handed to starter Chris Iannetta's right-handed bat. The backup figures to catch about 50-60 games.
