I think this is niche, but I bet McBeth really wants to be the one to achieve this. All numbers below are from last year's payouts or
this page
Paul is at $78. He will hit $100K in earnings this year if he:
1. Winning USDGC ($20k) and plays DGPT Finals ($2k)
2. Gets at least second at USDGC ($13k) and gets at least 3rd at DGPT Finals ($10k)
3. Gets at least third at USDGC ($7.5k) and gets at least second at DGPT finals ($15k)
4. Winning DGPT Finals ($30k)
Ricky isn't far behind at $68k. He could do it by
1. Winning USDGC and getting at least 2nd at DGPT Finals
2. Get sixth or better at USDGC and winning DGPA Finals
Simon or Calvin (both in the $50k range) can do it by winning both events.
Or, in what would be an awesome twist, McBeth could be usurped by his pal Kristen Tattar ($62k) if she wins USDGC and gets at least 2nd at the DGPT Finals. Honestly, this seems like the most likely way that it happens this year provided that her burned finger heals.
Paige Pierce ($50k range) could also do it she wins both, but it seems unlikely based on the past few events.
