Never heard of MJ Daffue? You’re not alone. Get to know the man out front at the U.S. Open

Making his major championship debut seems unfazed by the magnitude of the situation.

BROOKLINE, Mass. — Among all the big names near the top of the U.S. Open leaderboard, MJ Daffue is one many golf fans may not know.

He is making his major championship debut this week in Brookline, Massachusetts, at The Country Club and seems unfazed by the magnitude of the situation.

In Thursday’s opening round, Daffue shot a 67, good enough for a share of second behind only Adam Hadwin, who slept on the overnight lead alone at 4 under.

Daffue, a South African, had an early wake-up call Friday, teeing off at 6:56 a.m. ET, but he didn’t seem to mind. Through seven holes, he had four birdies on the card and led by three as he headed to the ninth tee.
