The Mariners have signed Greifer Andrade, the No. 21 international prospect for July 2, out of Venezuela.
While Andrade showcased for teams as an outfielder, he will begin his career as an infielder, starting at shortstop but perhaps moving to third base. Andrade, 16, had played third base in the past and some scouts liked his defense there. With his strong 6-foot, 185-pound frame and average speed, Andrade didn't project as a true center fielder, so the move to the infield makes him a more intriguing prospect.
Andrade stands out for his bat more than anything else. He was a standout on the Venezuelan team that won the 15U World Championship in Mexico last August, using a a line-drive approach with gap power. Andrade trains with Jose Aguiar.
