The 16-year-old netted the young Glovers’ equaliser, his third in as many games in the competition, before Joe Tomlinson and Paul Akinuli sealed victory with the Baggies grabbing a late consolation.
The Under-18’s stunning performance over the Premier League academy side sees them progress to the fourth round of the competition.
Morton told YTFC.net: “It was an unreal feeling scoring against a team like West Brom. It was such a great moment for myself and the team.
“I felt such a unbelievable feeling at full time and at the same time I was in disbelief.
“It was such a proud moment for all the lads knowing the effort we had all put in to achieve what we have so far.”
On who he would like in the next round, Morton added: “It’s got to be Manchester United – playing at Old Trafford would be unreal!”
