Brooks Koepka held a three-shot lead halfway through his second round of The Masters and Rory McIlroy is facing a battle to make the cut.

Koepka was joint-top of the leaderboard along with Jon Rahm and Viktor Hovland after starting with a seven-under 65 at Augusta National on Thursday.

The four-time major champion had the chance to go out on his own on Friday, with Rahm and Hovland starting later in the day, and he was sitting pretty at 10 under through nine holes.

Koepka arrived in Georgia full of confidence following a victory at LIV Golf Orlando and the American has given himself a great opportunity to win a first Masters title.

He birdied the second hole after an excellent third shot from a green-side bunker and eagled the par-five eighth following a majestic approach shot to move into double figures.

Jason Day surged into a share of second place courtesy of gains at the second and third holes, while a couple of early birdies took Collin Morikawa to five under on a day on which tee times were brought forward by half an hour due to the forecast of inclement weather.

Amateur Sam Bennett was six shots back from Koepka along with Sam Burns, Jordan Spieth, Tony Finau and Gary Woodland.

McIlroy's hopes of completing a career Grand Slam this weekend look to be over as he was back on two over through three holes following bogeys at the second and third holes.

Defending champion and world number one Scottie Scheffler dropped back to three under.
