Our most recent victory at the Riverside Stadium came in September 2009, as Roberto Di Matteo's Baggies made light work of their opponents, beating Boro 5-0.
A deflected Chris Brunt free-kick opened the scoring before he doubled Albion's advantage with an impressive side-footed volley from distance.
Youssouf Mulumbu notched a third before the break as the domination continued.
The Throstles added two more goals in the final 10 minutes, with Roman Bednar and Jerome Thomas both netting late on.
