Guwahati: Veteran left-arm spinner Jamaluddin Syed Mohammad registered his best first-class bowling figures to single-handedly give Assam an upperhand against defending champions Karnataka on the opening day of their Group A Ranji Trophy cricket match here yesterday.

Syed Mohammad spun the web around Karnataka batsmen to register his best bowling figures of seven for 44 and bundle out the title holders for a paltry 187 in 75.2 overs at Barsapara Cricket Stadium here after the visitors opted to bat.
