Sussex all-rounder Danial Ibrahim gave another demonstration of his outstanding promise with an unbeaten half-century on day three of their LV= Insurance County Championship encounter with Worcestershire at New Road.

Ibrahim celebrated his call-up to England U19s squad for the forthcoming one-day internationals against West Indies by making 56 not out to steer Sussex into a strong position.

He followed up his first-innings 48 and two for nine in nine overs in Worcestershire’s first innings with another accomplished knock.

His efforts, coupled with a second half-century of the game from Ali Orr, enabled Sussex to reach 199 for six in their second innings – an overall lead of 250 – despite three wickets apiece for Joe Leach and Josh Baker.

Worcestershire resumed on 186 for seven and the last three wickets fell for 27 runs in the space of 9.3 overs to earn Sussex a first-innings lead of 51.

Paceman Henry Crocombe dismissed Leach and Baker with successive deliveries – lbw and caught behind – while Fynn Hudson-Prentice held onto a return catch from Dillon Pennington.

The clatter of early-morning wickets continued during a devastating opening burst from Leach which reduced Sussex to three for three.

Sussex captain Tom Haines tried to work a delivery to leg and was caught off a leading edge by Tom Fell at first slip.

New batsman Harrison Ward went lbw to his first delivery from Leach and James Coles departed in the same manner.

The fourth-wicket pair between Orr and Ollie Carter flourished after lunch with the former completing his second half-century of the match from 96 balls.

They added 84 before spinner Baker broke the stand with an excellent return catch to dismiss Carter for 20.

Baker then picked up the key wicket of Orr, who presented the spinner with a far more straightforward caught and bowled to depart for 57, leaving the score 98 for five.

But a second substantial partnership of the innings was put together by Ibrahim and Hudson-Prentice.

Their stand was worth 87 before Hudson-Prentice, on 46, gave Baker the charge and was stumped by Ben Cox.

Ibrahim had time to complete his fifty off 120 balls with six fours before bad light ended proceedings at 5.30pm.
