Ryder Cup foursomes and four-ball are both team match play, but the partners use the ball differently. Foursomes is alternate shot with one ball for the side. In four-ball, each partner plays a ball and the relevant better score counts for the side on the hole. The similar names hide a substantial difference in what the camera is showing.

Read the session format before the first shot
A Ryder Cup programme can move between formats across sessions. Confirm which one is underway rather than assuming yesterday's structure continues. In foursomes, one partner's shot leaves the position for the other partner's next stroke. In four-ball, two balls from the same side can remain in play. A player not shown hitting may still have a ball elsewhere or may not need to complete a shot once the hole's result is settled under the rules. The format explains that apparent absence.
Keep the hole score as the immediate contest
Both formats use a side-versus-side match rather than adding every stroke from every player into one ordinary field leaderboard. The result of a hole changes the match balance. A large win on one hole does not create several holes of advantage. Read the match-play display, such as one up or all square, separately from the wider team points. The number of balls in play changes the tactics, but it does not change the need to identify which side won or halved the hole.
Watch the partnership choice
In four-ball, one partner's secure position can let the other consider a more ambitious option. In foursomes, the shared-ball sequence makes the next player's task part of every shot. Viewers can observe these relationships without claiming access to private strategy. Notice where both sides' balls lie and what result is still possible. A player walking toward the green is not necessarily disengaged; their next role depends on the format and the opponent's situation.
Use a two-hole comparison
Watch one complete hole in each format, noting who hits, how many balls remain and which score decides the hole. Then read the updated match balance. This is a clearer introduction than memorizing the names alone. Use the current Ryder Cup event schedule for session order and the current rules for exact procedures. An old edition guide can explain the concepts while still having outdated dates, venues or team-selection details. Keep those changing facts separate from the stable format distinction.
Useful answers
Does four-ball mean four players share one ball?
No. Each partner plays their own ball. The relevant better score supplies the side’s hole result under the rules.
Is foursomes the same as a four-person scramble?
No. Ryder Cup foursomes is an alternate-shot format for the two partners on a side. A scramble is a different form of play.
