However, recent struggles have seen him win just one event since November 2019, after his first win in 553 days at this year’s Wells Fargo Championship in May.
The world number 13 will therefore be no doubt targeting a second win – and an Olympic gold – in Tokyo this week, after his impressive second round put him in a strong spot heading into the weekend.
Team Ireland teammate Shane Lowry also enjoyed his round two outing after carding a superb six-under, 65.
Lowry’s playing partner, and Team GB athlete Tommy Fleetwood also made strides to move further up the leaderboard following his second round two-under, 69 left him three under par for the tournament.
Fleetwood’s British teammate Paul Casey continues his charge for a medal as the Englishman finds himself six-under for the tournament with seven holes of his second round to play.
