Osvaldo Bido

Athletics optioned RHP Osvaldo Bido to Triple-A Las Vegas.

The 29-year-old hurler has really struggled in his time with the A’s this season, registering a 6.14 ERA, 1.76 WHIP and a 34/23 K/BB ratio over 48 1/3 innings of work in 12 appearances. He’ll work to refine his craft at the Triple-A level until another opportunity arises with the A’s.
