The Pittsburgh Pirates have designated right-handed pitcher Wirfin Obispo for assignment to make room for Ramon Cabrera, who was claimed off waivers today from the Detroit Tigers. Obispo was claimed off waivers back in June from the Atlanta Braves. He has posted a 3.16 ERA in 25.2 innings with Indianapolis since the claim, along with a 24:13 K/BB ratio.

Obispo can still clear waivers, at which point the Pirates could outright him to Triple-A. However, he will be a minor league free agent at the end of the season if he doesn’t re-join the 40-man roster by that point. He’s an interesting prospect, with a 93-97 MPH fastball and a good history of strikeouts, but he’s also 30 years old, so he’s not really much of a prospect.
