The defender claimed the fourth goal in last week's 5-3 win against Norwich and was there again to volley home the equaliser as the team wrapped up their Premier Academy League campaign with a 2-2 draw at Villa.
The lads came from 2-0 down for a share of the spoils with Souleymane Coulibaly reducing arrears on 66 minutes and Stewart levelling four minutes from time.
"Even though we went behind, we played very well in the first half," reported coach Alex Inglethorpe.
"There was no rhythm to the second half, it was a bit stop-start, too many breaks in play, too many fouls and free-kicks.
"We conceded in the 25th minute when Villa threw the ball back to us after an injury, we lost concentration, lost possession and Villa scored.
"Villa scored their second on 65 minutes but we responded immediately.
"Jack Munns picked out Kenneth McEvoy down the right and Souleymane Coulibaly finished well.
"We equalised late on when Kevin Stewart found himself in the penalty area again and got himself on the end of a cross, a fine, low volley.
"Overall I was pleased. Villa always provide a real test, they've always had good Academy teams and I felt we controlled the game for long periods without really creating the chances to show for it."
Spurs U18s: McGee, A McQueen (Ward, 56), Stewart, Ball, Barthram, Veljkovic, Bentaleb, Lameiras (Oduwa, 56), McEvoy, Munns, Coulibaly.
