DeChambeau, 30, closed with a stunning 8-under 63 to prevail by one stroke over his fellow Crushers GC teammate Anirban Lahiri at LIV Golf Chicago.
The big-hitting American scooped a whopping $4.75m for his efforts on Sunday as he overturned an eight-stroke deficit at the start of the round.
DeChambeau fired shots at US Ryder Cup captain Johnson last night after landing his second LIV Golf title in his last three starts.
The former US Open champion revealed he never even received a call or any form of communication from Johnson despite shooting 61-58 to win LIV Golf Greenbrier just weeks before he made his six captain's picks.

Brooks Koepka was the only LIV Golf player to earn a pick in the team.
That meant no place for the likes of DeChambeau or even former World No.1 Dustin Johnson, who went 5-0 last time out at the 2021 Ryder Cup.
But speaking to a pool of reporters just hours after touching down in Italy for this week's Ryder Cup at Marco Simone, captain Johnson reposnded to DeChambeau's comments.
Given Johnson's response, it would seem like DeChambeau was never in the running for a pick in the first place.
Johnson said today:
Should Johnson have picked DeChambeau in the US Ryder Cup team?
