4. All the feels

Moriya Jutanugarn broke through for the first time at the L.A. Open, and the enduring image from that Sunday is little sister Ariya sobbing off to the side. It was undoubtedly the most fulfilling moment of Ariya’s year, and she won every award the LPGA had on offer in 2018. This was a family victory. It was also storyline that moved on throughout the season as incredibly two sets of siblings – the Jutanugarns and Kordas – hoisted trophies.
