Zhang, who is rising in the ranks, will now look for a fight with a top contender.
Undefeated Olympic bronze medal winner Filip Hrgovic (12-0) became the first man to scored a stoppage victory over veteran Rydell Booker.
Booker had taken punishment round after round, prompting the referee to wave off the fight in the fifth round.
Afterwards, Hrgovic called out most of the top heavyweights in the top ten.
In the main event of the card, WBC lightweight champion Devin Haney dominated Olympic gold medal winner and two-division champion Yuriorkis Gamboa over twelve rounds, for a unanimous decision win.
