The Marlins announced they’ve designated reliever Shawn Armstrong for assignment. Miami also optioned bullpen arm Zach Pop to Triple-A Jacksonville. The moves satisfy the requirement to cut active rosters from 28 to 26, and Armstrong’s designation brings Miami’s 40-man roster total to 39.

A designation was the only way to remove Armstrong from the big league roster. Like many of the players who have lost their 40-man spots in recent days, he is out of minor league option years.
