Last week, he conceded to Island View Golf Club pro Johnny Schwaller on the 17th tee in a Minnesota PGA match-play event at Mendakota Country Club.
On Thursday, golf store manager Derek Holmes competes in a major championship against Dustin Johnson, Rory McIlroy and 153 other professionals of both the touring and club kind.
He'll do so at South Carolina's famed, wind-swept Kiawah Island Ocean course, site of the Ryder Cup's 1991 "War on the Shore" and McIlroy's 2012 PGA Championship victory.
"It can blow 90 and I'll have a smile on my face," Holmes said.
At age 34, he is older, presumably wiser and definitely calmer than the former assistant club pro at River Oaks and Dellwood Country Club once known in his Minnesota PGA section for his talent and temperament.
Now a husband and father of a 2-year-old son, Holmes reached his first — and probably only — major by sinking a clutch, clinching 25-foot par putt on the PGA Professional Championship's 72nd and final hole last month in Florida.
That putt made him one of 20 players who advanced from the 312-player field. It made him the first Minnesota PGA section player to reach the PGA of America's national championship since Brent Snyder in 2015. (Transplanted Minnesotans Alex Beach and Ben Polland qualified from other PGA sections.)
It also made Holmes' phone buzz incessantly for days.
