Jon Rahm was seen shouting 'can I get one number right today' towards his caddie Adam Hayes after sending a short iron to within 30 feet of the pin on the par-3 11th in the final round of the Mexico Open.
The World No.1 was trailing Finau by three strokes as he played into the 11th hole but the lead was soon stretched to four strokes after Rahm two-putted for par and Finau rolled home a birdie from nine feet.
It was on that tee shot where a microphone picked up Rahm fuming over his yardage, which judging by his choice of words, was not his first bad number of the final round.
Angry at himself, or taking aim at his caddie? We'll let you be the judge of that one...

@JonRahmpga throwing same shade at his caddie because Rahm does everything right always. “Can I get one number right today.” Not cool. It’s either the caddie the wind or the greens fault.

Rahm was once again seen getting irate with his yardage when coming up short of the flag in the rough at the par-3 17th.
That led to a bogey and end any last-ditch hopes he had of defending the Mexico Open.
On-course commentator Colt Knost also noticed a number of wrong clubs for Rahm in the final round.
As Rahm came up short of the front greenside bunker with his second shot into the par-5 18th, Knost said: "Seems like some wrong clubs coming in."
Rahm went on to card a 4-under 67 to finish in solo second, three strokes behind Finau, who closed with a 66.
Finau finished the week on 24-under par.
The win marks Finau's sixth career win on the PGA Tour.
It was also redemption for Finau who finished runner up to Rahm at the 2022 Mexico Open.
Finau has now won four times in his last 18 appearances.
He's also landed six top-two finishes over the past 12 months.
Finau now returns to World No.11 and fourth in the FedEx Cup standings, while Rahm remains out in front at No.1.
Brandon Wu, who also finished runner up in this tournament 12 months ago, finished in third place on 19-under par.
Akshay Bhatia finished solo fourth on 18-under par.
