Emiliano Grillo and Matthew Fitzpatrick each earned a share of the early lead at the Arnold Palmer Invitational with at five strokes under par.
The two young golfers started on different tees and had very different days, but each finished with a 67 to take the lead after Round 1.
Lucas Glover, Paul Casey and Charley Hoffman all sit one stroke back after carding 68s in the opening round.
Here is a look at the latest leaderboard from Orlando:
Grillo had to play in cold morning weather, but that didn't stop him from scoring seven birdies, including a stretch of four in five holes on the front nine.
