Luke Wells made his second half century of the match as Sussex’s game against Yorkshire moved towards an inevitable draw.

Wells continued his display of resistance by taking almost four hours to reach his fifth Championship 50 of the season to ensure there would be no final day drama at Arundel Castle.

Together with Rory Hamilton-Brown they put on 110 for the second wicket as Sussex went to tea on 203-2, leading by 49.

Hamilton-Brown made his highest score of the summer before he was caught at leg gully off the bowling of Azeem Rafiq for 62.

Wells remains unbeaten on 74 – from 234 balls – while Matt Machan has come in at No.4 ahead of the injured Ed Joyce to score six so far.

Earlier, Chris Nash had dominated an opening stand of 66 with Wells before being caught at slip off Rafiq for 53.

With a draw the only likely result in the match the teams are expected to shake hands on a draw at 4.50pm.
