Nice, Matt! Great shot under the circumstances! I absolutely love Spyglass.
My "best" shot of the year is similar to yours, in that it's more the circumstances than the actual shot itself. Shot was a simple 80-yard LW approach on the par-5 18th hole at my home course in the final round of our club championship this year (Victoria Club, 6,570, 71.3/130)
We play "Red/White/Blue" tees in our championship. After rounds of 69 (red tees), 68 (white tees), I went into the final round 6-shots back of our current club champ, a 45 year old +2 to +4 guy who had won 10 of the last 11. Last year, my first year at the club, I beat him in the Match Play Club Championship, but lost to him by five shots in the Stroke Play. Knew I would have to play my very best to beat him and unfortunately shot myself in the foot when I shot just 69 from the red tees on day one, when he shot 65. He picked up another two shots the next day from the whites (my 68 to his 66), and as we teed it up on Sunday from the back tees, I was 6 shots back. I figured 65 should beat him or tie him.
Long story short(ish): I shot 4-under 31 on the front, to pick up two shots, but was still 4 back. Birdied 10, 15, and 17 to get to 7-under on the day and was just one-back standing on the 18th tee, a 545 yard par-5 with water fronting the green. Completely unreachable for me, but our defending champ is LONNNNG. 270 to 280 carry, 290 to 310 off the tee. With a good drive, he can reach for sure. I drove it down the middle and then laid up to 80 yards. The defending champ piped a drive 300ish and had 235 to a front-left pin. This was it. If he knocks it on in two, he likely birdies and I will have to hole out to beat him or hope he 3-putts.
Well ... he striped a cut 3-wood over the creek and onto the middle of the green and that was all she wrote. I took off my hat and applauded. What else could I do. I would now have to hole my LW and the best I could do was get it close on the first bounce but it sucked back to about 10-feet. All he had to do was 2-putt a simple 30-footer. He went first and lagged it up to 6-inches and marked. I made my 10-footer for an 8-under 64, the lowest round shot by three strokes in the 100+ year history of the club ... and he tapped in his birdie and I lost by one.
Still, the "old" me would have never, ever have been able to close with a 64 (that tied my career best and bettered my previous competitive best by two strokes). My nerves would have gotten to me somewhere along the way and I would have hit a really bad, untimely shot(s) somewhere. And I certainly would not have stood up to that LW on the final hole and knocked it dead at the hole and then buried the putt. I would have ... choked.
At 53 years old now, I'm playing the best competitive golf of my life when I can keep the back spasms at bay. If I can stay (mostly) pain free, I can do some damage as a senior am. Really looking forward to the competition.
