The 18-year-old young professional was drafted in alongside Chris Riley and Jacques Maghoma as the Academy struggled with a number of injuries.
Captaining the side, the midfielder scored two goals including the late, late winner as his double and one from Terry Dixon secured the 3-2 win.
Crewe capitalised on a couple of mistakes to forge into a 2-0 lead but there was no denying the lads once Terry Dixon pulled the first goal back just after the hour.
Goalkeeping coach Perry Suckling takes up the story. "The spirit from the boys was very good, even though we were 2-0 down at half-time there was belief in the changing room that we could come back and win.
"I felt we were unfortunate to be 2-0 down after two straight balls over the top that we didn't defend against.
"The second half was a different story. We changed it around at half-time and the lads played fantastically well in the second half - we could have scored three before we made it 2-1 through Terry Dixon on about the hour mark.
"Terry's goal came after some great team play, Stuart Lewis then scored a twice-taken penalty after 75 minutes and in the 89th minute, a couple of one-twos, Stuart ghosted in and bent it past the keeper for 3-2.
"It was a very good performance. We had one or two injuries going into it and the more senior boys did well for us and we had some Under-16s in there as well, so it was a mixed bag. It was a great start to the season for us."
