JERSEY CITY, N.J. — When I was a junior in college, I had a professor for a creative writing seminar who on the first day of class stood in front of the room and announced: âIâm not afraid to give everyone here an A, and Iâm also perfectly comfortable giving each of you an F. Youâll get what you earn.â Good times, that class. Iâm not sure what Professor Castle is up to these days (or if that was actually his name) but heâd probably enjoy dishing out grades for one of the most lopsided team events in golf history. In this edition, extra weight will be given to the first three days, given Sundayâs singles matches were rendered all but moot. Letâs get to it.
U.S.
Dustin Johnson (4-0-1) â A+
No. 1 in the world and played like it.
Jordan Spieth (3-1-1) â A
Never gave an inch while partnered with Patrick Reed. Raised game even higher Saturday after goofy rules controversy.
Patrick Reed (3-1-1) â A
Captain America improved to 8-3-1 when paired with Spieth in team events. The legend grows.
Justin Thomas (3-1-1) â A
Huge energy and played heroic golf. What an encore to a dream season.
Rickie Fowler (3-0-1) â A
Terrific week. Did much of the heavy lifting early in his matches while his partner Thomas served as closer.
Phil Mickelson (3-0-1) â A
Missed putt on 18 to win Thursday match, but whoâs gonna remember that? If this was his last Prez Cup as a player, the final chapter was oh-so sweet.
Kevin Kisner (2-0-2) â A
The Prez Cup rook flashed nerves and toughness while winning 2.5 points with Phil. Ready for a Ryder Cup team.
Matt Kuchar (2-1) â A-
Cruised along for two sessions with DJ. Smiling all the way.
Daniel Berger (2-1) â A-
Started slowly but gave JT big boost Saturday afternoon. At center of most high-octane singles match, clinched decisive point against the mad shusher, Si Woo Kim. Big future. 
Kevin Chappell (1-1-1) â B+
Came off bench on Friday with hair on fire, making three birdies in first nine holes. Halved singles match to guarantee U.S. would keep Cup.
Brooks Koepka (2-2) â B
Indestructible with DJ but didnât offer much else.
Charley Hoffman (1-2) â B-
Other half of cool âbash brothersâ celebration with Chappell. Went bananas after Saturday chip-in. Failed to clinch Cup in second Sunday singles match.
Captain Steve Stricker â A
Combinations clicked, team played free and loose all week. Prelude to a Ryder Cup captaincy?

INTERNATIONAL
Branden Grace (1-2-2) â B
Went unbeaten in Korea two years ago and battled for everything again this week, including singles-match halve vs. DJ.
Anirban Lahiri (1-1-1) â B-
Sure, he suffered a disastrous 6-and-5 Friday loss (with Charl Schwartzel), including a rules gaffe that had him DQâed from playing a hole. But saved face by drilling key late putts to win a Saturday point, preventing his team from enduring the humiliation of losing the Presidents Cup on Saturday. Picked up another .5 point against Kiz on Sunday. Not bad for a much questioned captainâs pick. 
Louis Oosthuizen (2-2-1) â B-
Wasnât as sharp as his sidekick, Grace. Clipped Reed in singles, even though it didnât matter.
Jhonattan Vegas (1-4) â C
Played with passion but dragged down by poor partners. Beat Spieth Sunday. Better than his record. Did Venezuela proud.
Si Woo Kim (1-2) â C
Came up clutch while winning Saturday match. Bonus points awarded here for shushing crowd while trailing in singles match and with team down by 11 points.
Marc Leishman (0-3-2) â C-
Had a few nice moments carrying Day. Hung on for half-point in opening singles match.
Adam Hadwin (0-2-1) â D
Showed grit while carrying Matsuyama to half-point Friday, but that was it.
Charl Schwartzel (1-2) â D-
Routed twice early and benched until singles.
Jason Day (1-3-1) â F
World No. 7 showed up Sunday ready to play. Too bad the event started Thursday. His career President Cup record is now 4-12-4.
Adam Scott (1-3) â F
Like his countryman Day, didnât wake up until Sunday.
Hideki Matsuyama (1-2-1) â F
Highest-ranked player on the squad sprayed tee shots all over New Jersey for three days. Beat JT in singles when pressure was off. Big disappointment. 
Emiliano Grillo (0-3) â F
The invisible man.
Captain Nick Price â C
What was he supposed to do? Couldâve tried different combos early in week, but none of it wouldâve mattered. Handled drubbing with class.
