Dimitrov downs plucky O'Connell at Open

Chris O'Connell has been ousted in straight sets by Bulgarian 15th seed Grigor Dimitrov at the Australian Open.

Dimitrov was untouchable on serve against the grand slam debutant, winning 7-6 (7-2) 6-3 6-3 in two hours and one minute on Tuesday night.

O'Connell stared down five break points to take the first set to a tiebreak but the 22-year-old wasn't able to maintain that level as the match continued.
