Maile was optioned to minor-league camp Wednesday, Marc Topkin of the Tampa Bay Times reports.
Maile, Curt Casali and Mike McKenry were all sent packing from big-league spring training, leaving Jesus Sucre as the No. 2 option behind Derek Norris to begin the 2017 campaign. The 26-year-old Maile fared well during Grapefruit League play (13-for-35) and he could get the call if there is an injury behind the plate while the Rays are still without Wilson Ramos (knee).
