Beigh claimed all the four Assam wickets that fell today to end with innings figures of 6 for 42, his first five-for in this Ranji season.
Riding on Beigh's early onslaught, J&K skittled Assam out for 195 before the home side batsmen chased down the target of 32 runs to give them their fourth win in six games.
Assam began the fourth and final day on a slippery 156 for 6 and they would have hoped to find a way to salvage a draw. Instead, Beigh struck between the 46th and 54th overs to bundle the visiting side out.
J&K achieved the target in 6.2 overs but lost opener Adil Rishi (13), thus wasting their chance of claiming the extra bonus point.
