The Pittsburgh Pirates will start right-handed pitching prospect Osvaldo Bido against the Cubs on Wednesday night, with Bido making his MLB debut.
Bido has always carried that sleeper tag on this site. Originally a low key international signing at age 21, he entered the game with the ability to hit mid-90s. Consistent mid-90s velocity is now one of his strengths, paired with a slider that can generate swing and miss.
This year in Triple-A, Bido has a 4.55 ERA in 55.1 innings, with a 56:26 K/BB ratio. He’s mostly worked out of the rotation, and will get the start tonight in place of Roansy Contreras.
