Brett D’Oliveira and Ben Cox produced an awesome display of post lunch hitting to help earn Worcestershire CCC a first innings lead of 161 on day three of the Bob Willis Trophy encounter against Gloucestershire at Bristol.

The sixth wicket pair plundered 92 runs in the final eight of the permitted 120 overs with a dynamic mixture of power and shot improvisation.

It followed on from an impressive maiden first class half century from Jack Haynes and enabled Worcestershire to total 428-5 from 120 overs.

Paceman Charlie Morris then struck a vital blow with the prized wicket of Gloucestershire captain, Chris Dent, shortly before the close after he had scored his second half century of the game. It was Morris’s sixth victim of the game as Gloucestershire closed on 135-3 still 26 in arrears.

D’Oliveira, who ended unbeaten on 91, said: “I think we’ve been consistent with what we’ve been trying to do with bat and ball and so far, it has paid off.

“Dent is a fine player and it was great to get him out. I think we actually deserved that wicket because we had been building some pressure towards the end.

“Going into tomorrow, it’s about building that pressure up again and hopefully we can get a cluster of wickets."

The icing on the cake was the D’Oliveira-Cox onslaught which helped secure a sizeable advantage. The tone was set as 28 runs were plundered off the first two overs after lunch and the pair produced a wide range of strokes.

D’Oliveira’s 91 not out came from 104 balls with 13 fours, to add to his two key wickets yesterday, while Cox struck 45 not out from 32 deliveries with one six and six fours.

Worcestershire had resumed on 223-2 and Tom Fell (39) was lbw to Josh Shaw after attempting to work a delivery to leg with 10 runs added. Haynes collected his first boundary with an impressive square drive at the same bowler’s expense and then pulled Graeme van Buuren to the ropes to secure a second batting point.

D’Oliveira found the second new ball to his liking with two fours in an over from Ryan Higgins. Worcestershire overhauled Gloucestershire’s first innings total of 67 when Haynes clipped David Payne off his legs for two.

The England Under-19 batsman completed his maiden first class fifty when he forced Payne through mid-wicket for his fourth boundary.

Haynes fine knock ended on 51 in the next over when he was lbw to Higgins after trying to force through the leg side with the total 281-4.

Riki Wessels raced to 19 off just 17 balls with four boundaries before he pulled a delivery from Matt Taylor and fell to a fine running catch on the deep mid wicket boundary by Graeme van Buuren.

It preceded the amazing onslaught from D’Oliveira and Cox after Worcestershire had gone into lunch on 336-5 from 112 overs. D’Oliveira completed an excellent half century with the first ball after the resumption from 79 balls and seven fours and then he and Cox accelerated in superb fashion.
