Jason Gillespie has revealed how he has been impressed by the grown-up Ollie Robinson – four years after showing him the door.

The Sussex bowler has been the backbone of his team’s seam attack in a demanding burst of five Championship fixtures.

Now he hopes for a crack at the 50-overs stuff with a seal of approval from his head coach at Hove.

Robinson is in a 14-man squad for today’s opening Royal London One-Day Cup fixture against Kent at Hove.

He comes into the game after 172 Championship overs as the one constant in the pace attack while others have been in and out of the side – or just out.

Gillespie was head coach at Yorkshire when they picked up the young Robinson after he moved north from his native Kent.

They liked what they saw with the ball but dismissed him after various breaches of discipline, none of which were believed to be serious.

That was in 2014. The paths of player and coach crossed again in Hove after Gillespie was named head coach in the close-season.

And Robinson, with a team-high 23 wickets to date plus a half-century against Middlesex with the bat, has responded in style.

Gillespie told The Argus: “He was at Yorkshire for a little while. To be fair to him, and he would probably admit it, he didn’t quite settle in there.

“He was a long way from home, he is a Kent lad.

“Everyone at Yorkshire acknowledged what a fine cricketer Ollie was.

“But, at the end of the day, he just didn’t quite settle into the life of a professional cricketer at Yorkshire County Cricket Club.

“That was a few years ago now. Being a bit closer to home, he is more settled.

“I think you just mature as a person, don’t you? He is a fine cricketer.”

Gillespie was tipped off about Robinson by the player’s stepfather Paul Farbrace, the England assistant coach.

He added: “He was up there in the leagues and Paul said would we be interested in having a look at him? We got him in and there were a couple of opportunities.

“He played some second team cricket and it went from there.”

Robinson was on the sidelines this time last year with a shin problem.

Luke Wells (knee) was also ruled out but has made no secret of his white-ball ambitions. The longer-haul RLODC could suit him.

It all rather fizzled out when Sussex donned the pink kit last term.

Back-to-back Hove dates against Kent today and Hampshire on Saturday give them the chance to get off to a flyer this time.

Sussex: from Brown, Briggs, Burgess, Evans, Finch, Garton, Rawlins, Robinson, Sakande, Salt, Sharma, Wells, Wiese, Wright.
