Making his debut in a Football League First Division match on 13 February 1904, the centre-forward quickly established himself in the Reds starting line-up but was unable to stop Liverpool's fall from the top flight at the end of the 1903–04 season.
The following season proved to be more fortunate for Liverpool as they regained their spot back in England's top division, Hewitt, however, only made 9 appearances, not enough to qualify for a winner's medal.
Hewitt did become a key player at Anfield in the 1905–06 campaign as he finished top scorer in the championship-winning side with 24 goals in 37 outings.
The 1909–10 season proved to be Hewitt's last for the club as he made just 4 starts, he was transferred to Bolton Wanderers in August 1910 after scoring 73 times in 164 appearances an average of a goal every 21⁄4 games.
