Blank Esports has been handed its first losses of 2017.

The sole Australian team in the Overwatch Pacific Championships was beaten by a pair of Taiwan-based teams over the weekend.

ahq eSports Club eked out a win over Blank 3-2 on Friday, and Flash Wolves swept the Aussies 3-0 on Sunday.

Blank did chalk up a win as well though, with a 3-1 victory over Taiwan's Machi Esports.

"So proud of our team being able to take 65 series back to back, shame it had to end and sad to let everyone down," tweeted Blank captain Andrew 'Rqt' Haws.

Despite the losses, Blank still sits atop the Pacific Championships table, tied with ahq eSports Club on 10 wins and two losses.

There are still six weeks remaining in the competition's 11-week regular season.
