WA teenager Albert Esterhuysen gave Sam Konstas an almighty send-off but it was NSW who had the last laugh in the One-Day Cup clash at the WACA Ground.
Esterhuysen, playing just his second one-dayer for WA, bowled Konstas for 40 and then unleashed an extended roar and stare-down in the Test opener's direction during an emotional celebration.
Konstas entered Thursday's match desperate for a big score to mount a solid case for an Ashes call-up, but he couldn't go on with the job after a strong start.

In reply, WA were bowled out for 244 in 46.5 overs, with the returning Mitch Marsh making just two as NSW cruised to an 87-run bonus-point victory.
