OLLIE Robinson, sacked by Yorkshire last season for “unprofessional actions” looked the model pro as he showed his new Sussex team-mates how to bat with a century on his first-class debut.

Given his chance because Tymal Mills (back) has joined Lewis Hatchett and James Anyon on the treatment table, the lanky 21-year-old went in with Sussex on 145 for seven and was still there on 110 in guiding them to 335 for nine at tea.

Matt Hobden has contributed 65 to the stand of 164, frustrating Durham after a spell of three for five in 13 balls by Chris Rushworth.

They resorted to trying to bounce out the last pair, but Robinson stood tall and looked totally assured in hitting 17 fours in his 101-ball century.

Cricket's regulations were made to look silly when tea was delayed because nine wickets were down when the stand was already worth 113.

The previous highest last-wicket stand against Durham was 146 between Glen Chapple and Peter Martin at Old Trafford in 1997.
