The Magpies bounced back from being thrashed 3-0 by Everton in midweek by beating the Baggies on Saturday afternoon with a much-needed victory.
Serbian striker Aleksandar Mitrovic hit the winning goal in the first half, latching on to a through ball from Shelvey before slotting past West Brom goalkeeper Ben Foster.
The win moved Newcastle out of the bottom three, and new signing Shelvey had a big role in that again, just as he did in the 2-1 home win over West Ham United last month.
Shelvey, 23, joined the Magpies from Swansea in January, and has already earned plenty of praise for his passing range and creativity, which was on show against West Brom - and pundit Garth Crooks has raved about him.
Speaking to BBC Sport in his Team of the Week column, Crooks felt Shelvey was even better against West Brom than he was against West Ham, and should thrive with new signing Andros Townsend running ahead of him too.
Crooks also felt that Newcastle really missed out on West Brom striker Saido Berahino, as they missed out on a late transfer window deal for the forward according to BBC Sport, with Crooks suggesting that signing him would've really pushed Newcastle away from trouble.
"This is the second time Jonjo Shelvey has made my team of the week since his move from Swansea," said Crooks. "His first appearance was on his Newcastle debut, however his performance against West Brom was even better. He seemed to spray the ball around St James' Park with consummate ease."
"The ball he provided for Aleksandar Mitrovic to go on and score past Ben Foster was just superb. With the arrival of Andros Townsend, Shelvey has another moving target to set his sights upon. What a pity Steve McClaren couldn't convince Saido Berahino to sign for the Magpies in the transfer window. Add a player like that into the mix and suddenly Newcastle are cooking with gas again," he added.
What did you think of Shelvey's performance? Did Newcastle miss out by failing to land Berahino?
