From the beginning of the bout, the two boxers went at each other and stayed close throughout the scheduled 10 rounds.
Isaac 'Royal Storm' Dogboe’s hand in the bout on Saturday night was faster than his opponent with a counter-punching ability which was an improvement of the Ghanaian’s previous bouts.
Under the scorecard of two of the judges, Terrence Crowford and Shawn Porter, Isaac Dogboe won over Christopher Diaz.
Judges Tim Cheatham and Don Trekla scored Diaz and Dogboe 96-94 and 97-93 respectively while judge Eric Cheek scored the two boxers 95-95.
The result makes the former super bantamweight champion move a top-notch higher in his third straight victory while he aims to grab a second world title.
