The Pirates have formally announced the signings of second-round pick Kevin Kramer (who we already noted elsewhere) and three other draftees: 20th-rounder Tanner Anderson, 21st-rounder Nicholas Economos and 30th-rounder Mike Wallace. Kramer will head to Morgantown, Anderson and Wallace will go to Bristol, and Economos will go to the GCL.
Anderson is a college senior (a righty from Harvard), so it's unsurprising that he signed. Economos was a junior-college pitcher, but I don't believe he was committed to a top college program. Wallace was a junior at Fairfield in Connecticut. None of them appear to be top prospects, but at this point, you never know.
