Welcome to the 2024 Men's Australian Open Bracket Challenge presented by @tennis.facts.and.stats on Instagram! The brackets will close when play begins on Sunday (or Saturday night depending on what time zone you're in), so get your picks in before then. Also, make sure to click the "Update" button at the bottom of the bracket to make sure your picks get saved. Any updates for withdrawals and lucky losers can be found on my Instagram stories.
