Ollie Robinson was named winner of the 'Porsche Performance of the Month' award for August following his stunning 14-wicket haul against Middlesex.
The fast-bowler's figures of 14-135 were the best by a Sussex bowler since 1964, and secured his side a emphatic seven-wicket win.
After Robinson's incredible performance, captain Ben Brown said: "To carry the bowling attack like that was outstanding. He's an unbelievable bowling machine at the moment. If there is a better bowler in the country at the moment I'm not sure where he is.
"It's never too many overs for him. He just keeps coming and coming. He's growing as a professional and that's really showing on the pitch."
Robinson's showing against Middlesex was one of four performances shortlisted in a poll voted on by the @SussexCCC followers on Twitter.
Phil Salt, who hit 78 off 32 against Glamorgan in the Vitality Blast, Alex Carey, who also starred against the Welsh side with 61 off 30, and Delray Rawlins, who smashed 69 off 41 against Gloucestershire, were the other nominees.
