Springbok centre Andre Esterhuizen bagged a brace of tries as Harlequins beat Bath 31-17 at The Stoop on Saturday.
Premiership champions Harlequins made it four bonus-point wins from five games as they erased a half-time deficit to defeat Bath by 14 points.
Quins raced to a 12-3 lead courtesy of two tries from Esterhuizen.
But Bath took advantage when Harlequins were reduced to 14 men after Joe Marler was yellow-carded, with Sam Underhill and Will Stuart going over for tries to give the visitors a 17-12 lead at the break.
After half time, Marcus Smith darted over for a superb individual try as Quins regained the lead.
Joe Marchant then went over for the bonus-point try before Smith’s second touchdown completed a fantastic second-half comeback.
