Alan Pardew claimed his first win as West Brom manager with a 2-0 FA Cup victory at Exeter.
First-half goals from Salomon Rondon and Jay Rodriguez secured Albion's safe passage to the fourth round and gave Pardew a first win in nine games since succeeding Tony Pulis at the end of November.
Albion could even afford the luxury of a Hal Robson-Kanu penalty miss just before half-time, the Welshman sending his tame attempt too close to Exeter goalkeeper Christy Pym.
West Brom had gone 21 games without a win since beating Accrington in the Carabao Cup in August, but Pardew's most recent FA Cup memory was sending out a Crystal Palace side to contest the 2016 final.
