Athletics designated RHP Geoff Hartlieb for assignment.

With Mark Leiter Jr. (hip) returning from the injured list on Friday, someone needed to get the boot from the A’s bullpen and it looks like Hartlieb drew the short straw this time around. Hartlieb posted a 5.19 ERA, 1.62 WHIP and a 3/3 K/BB ratio across 8 2/3 innings in his four appearances with the Athletics.
