The BA and MLB writeups on Orelvis Martinez are easy to find and have been reposted several times so I won't include those here. Instead I'll link the following writeup from the February showcase in the Dominican which actually includes two MLB scout quotes, as reported by César Augusto Márquez for La Vida Baseball
SS Orelvis Martínez
Born Nov. 19, 2001, in Santo Domingo, Dominican Republic
6-foot-1 / 190 pounds
Projected club: Toronto Blue Jays
Other than Juan Pablo Martínez, no prospect may be more coveted than Orelvis. The Blues Jays, who last summer made a big splash by signing the hard-throwing Brazilian Eric Pardinho, are homing in on another talented teenager. Orelvis is a right-handed hitter with a compact swing, smooth mechanics, good extension and gap power. While not a speedy runner, defensively he has soft hands, an above-average arm and decent range to both sides.
“He is the most talented player coming out this year. He can hit to any part of the field. And he has pop, which is very good for a player who is still developing,” a scout for a team in the American League East told La Vida Baseball.
“Orelvis should take less than five years to make it to the major leagues. The question is whether it will be as a shortstop or, because of his height, as a third baseman,” said a scout for a team in the National League West.
OF Amell Brazoban is listed as 5'11 165 pounds, here is some batting practice footage of him:
