Taylor Guerrieri a pitching prospect who was the Rays’ first-round pick in 2011 has been suspended 50 games after testing positive for a drug of abuse. It was his second violation and Marc Topkin of the Tampa Bay Times reports that the drug is believed to be marijuana.

He’ll start serving the 50-game suspension at the beginning of next season but it’s essentially meaningless because he’s expected to miss most of the year following Tommy John elbow surgery anyway.
