J.J. Spaun holds the outright lead at halfway at the FedEx St. Jude Championship while 2022 Open Championship winner Cameron Smith made his move and Rory McIlroy and Scottie Scheffler missed the cut.

Spaun had shared the lead with Kim Si-woo after the opening day at TPC Southwind and backed that up with a three-under-par round of 67 to lead at 11 under after 36 holes. The American maintained his lead with five birdies along with two bogeys in his round.

Kim slid down the leaderboard after a three-over-par round with Sepp Straka, who finished with three straight birdies, and Troy Merritt in joint second at 10 under behind Spaun, with Denny McCarthy one shot behind them.

Merritt, McCarthy and Smith all carded five-under-par rounds of 65, with the latter moving up the leaderboard with birdies and an eagle on the par-five 16th hole.

The Australian is eight-under-par after two rounds, equal with Brian Harman, Tony Finau and Ryan Palmer.

Kevin Kisner is a further shot back after seven birdies highlighted his round of six-under-par 64, but that was bettered by both Tyler Duncan and Will Zalatoris.

Duncan and Zalatoris carded rounds of 63, with the former going bogey free and draining seven birdies to move into joint ninth.

Zalatoris had shot a first-day 71 but improved with seven birdies across a bogey-free round too, but is six under overall.

McIlroy headlined the list of names to miss the cut, with three bogeys holding him back, including one on the 18th hole, as he shot 69 to fall short by one stroke.

World number one Scottie Scheffler also failed to make the cut, despite an improved second round, not helped by a double bogey on the par-four ninth hole.
