Graterol so far has followed old Bert's mantra: Stay Back (on the rubber), Stay Tall (in posture), and Work out Front (with your release point). This bodes well for his effectiveness and his longevity.
Also, the stock photo of Graterol must be from when he was 17 years old. After his debut, I watched him bump chests with Miguel Sano. Brusdar Graterol is virtually the same size as Sano. 268 pounds is a fair estimate. He is a large, muscular young man.
