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.
