Top Rank will follow a successful formula on July 27, when they have Zou Shiming headlining again in Macau at the Venetian, with world title fights set for the undercard.

Shiming (1-0, 0 KO) won his pro debut on April 26 in front of a great crowd on what turned out to be a fantastic card top-to-bottom, overflowing with competitive, exciting fights. The two-time Olympic gold medalist was paid $300,000 for his pro debut, a jaw-dropping sum, but in the end, it seems a worthy business investment. The fighter is already drawing crowds that rival just about anyone in the sport.

This time, he'll face Mexico's Jesus Ortega (3-1, 2 KO) in a six-round bout.

For most fans, though, the real fights will come on the undercard again. Juan Francisco Estrada (24-2, 18 KO), who upset Brian Viloria in April for the WBA and WBO flyweight titles, will face mandatory challenger Milan Melindo (29-0, 12 KO). Melindo also won on the first Macau card, beating Tommy Seran.

Evgeny Gradovich (16-0, 8 KO) will make his first defense of the IBF featherweight title against Mauricio Javier Munoz (26-3, 12 KO), and heavyweight prospects Andy Ruiz Jr (18-0, 12 KO) and Joe Hanks (21-0, 14 KO) will also meet.

HBO2 will again air the show on a tape delay, with Ruiz-Hanks set to headline that night's Solo Boxeo Tecate on UniMas, also on tape delay.
