Crewe boss Steve Davis was full of praise for Kiwomya for his match-winning cameo.
“The two subs changed our fortunes and Alex showed two moments of quality to win the game, with the pass through to Lowe and then he scored his solo goal," he said.
“He showed a burst of pace, some really quick feet and then some composure to finish it lovely in the corner. I thought he was going to smash it but he has finished it in the corner."
