The days of Epy Guerrero dominating and bringing all the top Dominican talent to Toronto are passed, as Guerrero is more of an independent scout nowadays. He has his own training academy and the Dominican Baseball Guy found some cool pics of him and his academy at Joao Canziani's Flickr page.
But the Blue Jays are obviously active in the international market, as they recently signed seven Latin American prospects, including three Dominicans. The Jays signed pitchers Alberto Tirado, Yeyfrey del Rosario, and Jairo Labourt.
No data on any of these Dominican peloteros. See ya in five years guys, if you're great...and lucky.
