The Pirates have signed Dominican outfielder Jeremias Portorreal for $375000 Ben Badler reports. Badler's report is about as good as we typically get about the signing of a 16-year-old who isn't Miguel Sano so there's at least some information here. Portorreal is 6'2 he figures to be a corner outfielder or first baseman and he might one day hit for power.
