LONDON - Spain’s Jon Rahm overcame nerves and a two-shot penalty to claim victory at the Memorial Tournament on Sunday and replace Rory McIlroy at the top of the world rankings. Rahm began the final round at a steamy and gusty Muirfield Village Golf Club with a four-shot lead and padded that to eight with nine holes to play, but late drama saw his advantage shrink to three before the 25-year-old sealed his fourth PGA Tour win. Rahm, who joins childhood hero Seve Ballesteros as the only Spaniards to hold the top ranking, celebrated with a massive fist pump in fading light and near silence with spectators still banned due to COVID-19 restrictions. “I don’t know how to describe it,” said Rahm. “It’s been a goal since I was 13-, 14-years-old. “I remember I heard a story on the radio from my swing coach back in Spain, Eduardo Celles. We were driving somewhere and he asked me what my goals were and my ambitions and this and that, and I remember telling him I’m going to be the best player in the world.”
