Republic of Ireland international Callum Robinson claimed his first goal for West Brom since his permanent switch last week as the Baggies eased past Harrogate 3-0 to book their spot in the Carabao Cup third round.

Robinson booked Albion's progression with 13 minutes left, tapping in after Edwards' excellent darting run.
