Wales hadn't created any significant chances in the first half, but found themselves back in the game within minutes of the restart. It was sloppy from Scotland, who gave the ball away on the right, but Wales' Cavan Williams low ball across the box was excellent, putting the ball on a plate for Issak Davies to finish high into the net.
Scotland continued to create more chances but they weren't able to extend their lead. First, Gilmour's run down the right and ball into the box only needed a touch, but his cross evaded everyone. Then, Semple went close to scoring his third after he headed McGrath's cross from the right onto the bar.
After 60 minutes, Wales started to grow into the game thanks to a few positive substitutions. Cavan Williams should have equalised after finding himself in loads of space on the left side of the box, but his shot was straight at Scotland goalkeeper Ryan Mullen.
Davies was next to go close. The striker did extremely well to bring down a long ball on the run, before cutting inside his defender. His right footed shot from the angle was heading for the top right corner, but Mullen intervened to turn it round the post.
Wales substitute Jack Vale in particular was making a good impact on the game. With the pressure on their goal increasing, Scotland failed to clear a corner and the ball dropped in the area to Vale's feet. After shifting the ball onto his right foot, Vale found himself in space and managed to fire an effort on goal that flashed wide of the left post.
Scotland's substitutes were not having the same effect. Karamoko Dembele looked bright and dangerous on the right of the pitch, his touch was superb and he looked capable of beating his man with ease, but any threat that he could've offered was diminished when the 13 year old was moved into the middle of the attack.
Scotland were unable to get out and a Wales goal looked inevitable. Mullen had to relied upon again, this time to deny Vale after he had been slipped through on goal, palming his low effort wide of the post.
There was nothing Mullen could do, however, about Wales' equaliser. It came from the resulting corner, which Scotland must have thought they'd dealt with after heading clear. Instead, the ball dropped to Keenan Patten on the edge of the box and his first time, left foot volley flew straight into the far corner.
Scotland's players collapsed onto the pitch at the final whistle, but a draw means that they can still win the Victory Shield against Ireland on Friday. The Scots will have to win, though, as Ireland have won both of their games so far.
