The Liga Endesa’s top two have been eliminated at the quarter-final stage of the 2016 Copa del Rey but Real Madrid and Laboral Kutxa passed their respective tests in a thrilling start to the Kings Cup.

League leaders Valencia were stunned 83-78 by a Gran Canaria unit that simply would not give up.

On multiple occasions, Valencia looked comfortable with the duo of Fernando San Emeterio and Bojan Dubljevic, putting them up 26-16 after one and again 65-57 at the end of three but Las Palmas were determined not to be bullied into submission and eventually they gained the advantage late on which they never relinquished.

Pablo Aguilar paced the victors with 16 points.

Gran Canaria will meet Bilbao in the semi-finals as they toppled Barcelona 73-72 in what was an equally as stunning upset as Las Palmas’ effort.

Bilbao were made to sweat in the last few seconds as Brad Oleson drained a triple with 35.0 seconds left for Barca to narrow the gap to 73-71. Then with 3.2 to go, Tautvydas Slezas was handed a relatively soft unsportsmanlike foul as he was adjudged to have manhandled Ante Tomic.

Tomic made just one of his two foul shots though and Bilbao’s defence stood strong for the final 3.2 seconds to secure the win.

Alex Ruoff led Bilbao with 18 points in just 19 minutes on court.

Laboral Kutxa came through in the end, beating hosts Rio Monbus 79-77 with Adam Hanga pouring in 20 points for the victors.

But they had to rely on poor free throw shooting down the stretch by the hosts in order to get the job done. After a strong start, Laboral Kutxa were pegged back and then looked in danger of being another seeded team getting dumped out.

But a strong fourth quarter secured a narrow win for Vitoria as they go on to the last four.

And they will meet Real Madrid, the only seeded team that looked at ease in the quarter-finals as they brushed aside Fuenlabrada 101-84.

After a close first quarter, the reigning league champions broke the game open in the second quarter, taking a comfortable 54-34 lead and never looking back.

Jaycee Carroll had 18 points for Real as he hit four three-pointers from eight attempts.
