Baker made his professional debut on 6 September 2003,
stopping Dave Clarke in the first round. The highlight of Baker's career was competing in the
heavyweight edition of the
Prizefighter series on 2 October 2009. He entered the tournament as an outsider, but defeated one of the favourites—
Danny Williams—by
unanimous decision (UD) in the opening round, while also scoring two
knockdowns against Williams in the first round of their fight. In the semi-final, Baker was eliminated after losing a UD to
Coleman Barrett. ==Professional boxing record==
