The lanky outfielder was signed by Pirates scouts Rene Gayo and Ellis Pena. Polanco played his first professional season in 2009, hitting .306 in the Dominican Summer League.
He came to the United States as an 18-year-old and played the 2010 season with the Bucs' affiliate in the Gulf Coast League. He escalated quickly through the Pirates' farm system before making his much-anticipated Major League debut on June 10 this season.
