The Florida native traded nine birdies with six birdies in two laps around Jupiter Hills Club. Maguire would end the day two strokes clear of the closest competitors, Tyson Alexander, Joaquin Niemann, and Eugene Hong with the first two surviving a 3-for-2 playoff for the last two qualifying spots out of Tequesta. Maguire boasts a stellar college resume and is currently 6-for-10 on the Web.com Tour this season including a T5 at The Bahamas Great Abaco Classic. This will be his second appearance at the U.S. Open, finishing T58 at the 2015 edition. Notables that fell shy include: Tim Wilkinson (1-over 141), Robert Allenby (2-over 142), and Zach Wright (4-over 144).
