Jon Rahm lived up to his billing as the hottest talent in professional golf after starting his week at the Arnold Palmer Invitational with a seven-under 65 on Thursday.

Rahm, the world number one, boasts five wins from his past nine starts worldwide and has not finished an event outside the top 10 since finding himself in a tie for 15th in August's Tour Championship.

Coming off a victory in his most recent outing at the Genesis Invitational, Rahm is looking to secure another of the PGA Tour's new elevated events, with the increased prize pool drawing 44 of the world's top-50 players to the famous Bay Hill course.

He certainly made a promising start in Florida, heading into day two with a two-shot lead at the top of the leader board.

Rahm began his day with three consecutive birdies and finished with another two on 17 and 18 having carded an eagle on the par-five 16th.

His sole bogey came on hole eight, failing to recover a par after a wayward tee shot.

Another competitor coming off a win in his most recent start, last week's Honda Classic champion Chris Kirk is tied for second at five under with Cameron Young and Kurt Kitayama.

Not a single player finished their round bogey-free, but Kitayama and Max Homa (two under) made it through 17 holes before their first blemishes came on the 18th.

The group tied for fifth at four under includes some of the game's biggest stars, with world number two Scottie Scheffler joined by three-time major winner Jordan Spieth, Patrick Cantlay, Xander Schauffele and resurgent fan favourite Rickie Fowler.
