The Mariners announced they’ve selected righty reliever Zach Pop onto the big league roster. Rookie starter Logan Evans was optioned back to Triple-A Tacoma to create an active roster spot. Seattle had two openings on the 40-man roster.

Pop will make his team debut whenever he gets into a game. He joined Seattle in mid-April on a minor league deal. That came after he was released by the Blue Jays. Pop was battling elbow inflammation at the time, but he got back on the mound by the middle of May. He made two rehab appearances in the complex league before reporting to Tacoma. Pop has made 11 appearances and tossed 9 2/3 innings, allowing seven runs (though only three were earned). He has fanned nine against five walks.

More to come.
