Having spent most of his career working as a club professional[a] in Southern California, he received attention after making the cut and finishing in the top 15 at the 2023 PGA Championship at the age of 46.

[7] Block was born on June 15, 1976, in Reno, Nevada, growing up first in Davenport, Iowa, and then the St. Louis area of Missouri.

[15][16] He received wider attention after making the cut at the 2023 PGA Championship, the only club professional to do so.

[11][17] Another even-par 70 on the third round, for which he was paired with Justin Rose, saw Block move into a tie for eighth place after 54 holes.

[27] Block nevertheless secured a place in another PGA Tour event when he qualified for The American Express, by winning his Southern California section championship in late September,[28] and was later invited to play at the 2023 Australian Open, where he made the cut and finished tied for 27th.
