Michael Brennan went shirtless during the first round of the Zurich Classic of New Orleans on Thursday after finding his ball in a shallow, muddy water hazard on the par-5 18th hole and attempting to play it out. The moment went viral, and Brennan and his partner Johnny Keefer still managed to card an 11-under 61, going 7-under on their front nine to finish three shots off the early lead. Alex Smalley and Hayden Springer were among the leaders as the afternoon wave continued.
