Valdespin was designated for assignment after Friday's game, Joe Frisaro of MLB.com reports. After an 0-for-3 showing Friday in his first start of the year with Miami, Valdespin was bumped from the 40-man roster to create room for Saturday's starter, Adam Conley. The 27-year-old Valdespin has hit .287/.342/.378 with one homer and six steals in 60 games with Triple-A New Orleans this season.
