His inspiration may be the NSW State of Origin team but Australian wildcard Alex De Minaur has still emerged as a Brisbane International dark horse after again pulling off what few Blues teams can - winning in Queensland.
Sydney-born, Spain-based De Minaur, 18, continued his giant-killing run when he booked his first tour semi-final berth by overcoming American Michael Mmoh 6-4 6-0 at Pat Rafter Arena on Friday.
World No.208 De Minaur uses a "Blue Wall" cry to pump himself up during matches in a nod to his allegiance to NSW.
While the Blues haven't had much luck - losing 11 of the past 12 Origin series - De Minaur has only had good fortune channelling them on court in Brisbane.
Perhaps even more remarkably, the dyed-in-the-wool Blues supporter has been embraced by the Queensland crowd.

De Minaur backed up from his shock straight sets second-round win over former world No.3 Milos Raonic.
"The best way to describe this is at the moment is I'm in this really good dream and I really don't want to wake up - just disbelief, really," De Minaur said.
With mentor Lleyton Hewitt screaming encouragement court-side, De Minaur saved three break points in the sixth game to find his range and clinch the first set in 49 minutes with a booming forehand winner.
The second set became a blur as De Minaur dominated, thrashing 17 total winners to Mmoh's nine.

The Australian ended a spirited run by Saudi Arabia-born and raised Mmoh, who is the son of a Nigerian former tennis player and an Irish-Australian nurse.
