But the big news coming out of the day wasn't massive field sizes or huge prize pools, it was two different players having the kind of day most online pros only dream of.
Alex "AJKHoosier1" Kamberis started it all off, as the well known pro chopped the PokerStars Sunday Warm-Up to earn six figures, then went on to win the site's $200 Rebuy for around $40k.
But even Kamberis had to marvel at the work of Jordan "Jymaster11" Young.
Young booked his first six-figure score of the day by winning Full Tilt's Sunday Brawl, then went on to win that site's biggest event as well - the $750k Guaranteed.
Adding another $130k-plus to the day's earnings brought his total to well over $235,000, making Jymaster11's Sunday the stuff of legend by Monday morning.
With 8,197 players in the Sunday Million on PokerStars, the winner there would have a chance to outpace Young's earnings with one single tournament win and aqua44 did just that, earning $245,914.05 for a win without a chop.
Meanwhile, as six-figure scores were being handed out left and right, several top pros managed to have big Sundays.
Adam Geyer finished second to Intervention in the Full Tilt Sunday Mulligan to earn $36k, Dan Kelly finished runner up to threatnasty in the PokerStars Sunday Second Chance for a little under $40k, and Melanie Weisner took third in the PokerStars Sunday 500 to add $50,297.50 to her ever-growing bankroll.
