Luka Dončić (age 19.2 years) had his first triple-double as a pro vs Real Betis. He went 17p-10a-10r and propelled Real Madrid to victory 104:89 on the road in Seville. The last time someone had a triple double in the Spanish league or even Euroleague was 11 years before that (triple doubles are not common in Europe due to how the game is played).
