Neil Robertson failed to build on his superb defeat of Ronnie O'Sullivan as Barry Hawkins claimed a place in the semi-finals of the Ladbrokes World Grand Prix.

Robertson eased past five-time world champion O'Sullivan 4-1 in their second-round meeting on Thursday afternoon but was unable to replicate that form later as he lost 4-2 to Hawkins in the last eight.
