SEATTLE -- Right-handed relief pitcher Emilio Pagan couldn't get enough key outs to stay with the Athletics much past April.
A key acquisition in the team's offseason trade with Seattle for first baseman Ryon Healy, Pagan, 26, was optioned to Triple-A Nashville on Wednesday afternoon to make room for Brett Anderson, who started Wednesday's game vs. Seattle.
Pagan has been scored upon in eight of his 12 appearances this season and has a 5.93 ERA.
"We like his arm, and we feel like he is going to be a big part of this for us going forward," Oakland manager Bob Melvin said.
