Smith led the Wolves to four wins from four in March – including a 14-try romp against Harlequins and impressive victories over the past two Super League champions, Leeds and Wigan.
Tireless hard-tackling back rower Westwood was up against team-mate Matty Blythe and St Helens half-back Jonny Lomax for the official Engage Super League Player of the Month title but took the prize after gaining most support from the Engage Super League coaches.
Salford’s Jodie Broughton, who scored four tries in a win at Catalan Dragons, takes his place on the wing, Huddersfield full-back Scott Gris takes the Number 1 shirt whilst Wakefield skipper Glenn Morrison is named in the second row.
