Description Zayas (22-0, 13 KOs), a San Juan native, hopes to impress the partisan fans with a historic victory. If he bests Baraou, he’ll become the first Puerto Rican boxer to unify world titles on home soil. Baraou (17-1, 9 KOs), a German pressure fighter making the first defense of his world title, has won eight straight since a disputed split decision loss to Jack Culcay. His last five bouts have come on away soil, including last August’s unanimous decision over Cuban star Yoenis Tellez in Orlando, Florida.
