Gudino, 16, is six-feet tall and 150 pounds and comes from Maracay, Venezuela. He trains with former Major League shortstop Carlos Guillen in his hometown.
The youngster helped captain Venezuela to a championship at the 15U World Championship last August in Mexico, batting .458 with a .611 on-base percentage and a .833 slugging percentage.
Scouts say that Gudino is a polished and solid defender for his age with a slightly above-average arm. He's proven to be a good baserunner with average speed, and has been called a typical two-hole hitter despite a limited power stroke.
The Blue Jays also inked center fielder Freddy Rodriguez, also from Venezuela. Rodriguez is 6-foot-1, has above-average speed, and is ranked the 18th best international prospect by Baseball America. He, like Gudino, attends Guillen's academy.
Also among the signees were shortstops Jesus Ramirez and Miguel Almonte from the Dominican Republic.
