What Is the Modified Alternate Shot Format in Golf?

By Spencer Lanoue
November 2, 2025

Modified Alternate Shot, often called Greensomes, is a popular two-person team format that blends strategy, teamwork, and a unique rhythm that’s different from your typical four-ball or scramble. It's a fantastic game that reduces the pressure of a bad tee shot while still demanding smart planning and execution from both partners. This guide will walk you through exactly how the format works, how it differs from similar games, and the best strategies to use so you and your partner can come out on top.

Understanding the Basics: What is Modified Alternate Shot (Greensomes)?

So, what sets this format apart? At its core, Modified Alternate Shot is designed to give both players on a team an active role on every hole, starting at the tee box.

The fundamental premise is simple: it’s a two-person team game where both players hit a tee shot. From there, the team chooses the one ball they want to play for the remainder of the hole. The player whose tee shot was not selected picks up their ball and hits the team's second shot. From that point on, the two partners continue hitting alternating shots until the ball is holed.

This "modified" approach is what makes the format so appealing. Unlike traditional Foursomes (or Alternate Shot), where a single bad tee shot can put a team in a terrible position, this format gives you two chances to find a good spot in the fairway. It creates a fun dynamic of risk and reward and places a heavy emphasis on partner communication.

How the Game Is Played: A Hole-by-Hole Breakdown

Let's walk through an entire hole to see how the flow of play works in practice. Imagine you and your partner, Alex, are on the tee of a par 4.

1. On the Tee Box

Both you and Alex hit your drives. You slice yours slightly into the right rough, but it’s sitting up nicely. Alex hits a perfect draw that lands in the middle of the fairway but is about 20 yards behind your ball.

2. The Decision

After both tee shots are complete, you and Alex walk up and look at the two balls. This is the first critical strategic moment. Your ball is further down the hole, but it's in the rough and has a tree partially blocking the direct line to the green. Alex’s ball is in a pristine lie in the fairway with a perfectly clear shot.

You decide Alex’s shot, though shorter, gives the team the best chance for a successful second shot. It’s the higher percentage play.

3. Playing the Second Shot

Since Alex's ball was chosen, you are the one who has to play the second shot. Alex picks up their ball but leaves their chosen ball there for you. You step up and hit the approach shot onto the green.

4. Finishing the Hole in Alternate Shot

The ball is now on the green, about 20 feet from the hole. Since you hit the second shot, it's Alex's turn to putt. Alex putts the ball to about one foot from the cup. It’s now your turn again, and you tap in to finish the hole.

You score a 4 on the hole. The rotation is complete, and you move to the next tee, ready to do it all over again.

How Modified Alternate Shot Compares to Other Team Formats

One of the reasons golfers sometimes get formats mixed up is due to subtle differences in the rules. Let's clarify how Modified Alternate Shot stands apart from other popular team games.

Modified Alternate Shot vs. Standard Foursomes (Alternate Shot)

In a standard Foursomes format, partners decide ahead of time who will tee off on the odd-numbered holes and who will tee off on the even-numbered holes. If your partner tees off on hole #1, you hit the second shot, they hit the third, and so on. You don't get two chances at a drive.

  • Key Difference: Foursomes has only one tee shot per hole. Modified Alternate Shot has two. This makes an enormous difference, as the pressure on the tee shot is much higher in standard Foursomes.
  • Why it matters: Greensomes is often seen as a less intimidating version of Foursomes, ideal for players who might not feel confident hitting every other drive for an entire round.

Modified Alternate Shot vs. Chapman System (Pinehurst)

The Chapman System is another two-person format that can seem similar on the surface but has one major twist after the tee shot. Like Greensomes, both players hit a drive. But this is where it changes.

In Chapman, the partners switch balls for the second shot. Player A hits Player B’s ball, and Player B hits Player A’s ball. After both second shots are hit, the team then chooses the single best ball to play from that point, and they play alternate shot from there to finish the hole. The player who hit the ball that was picked up hits the team's third shot.

  • Key Difference: Chapman involves two tee shots and two second shots before the alternate shot sequence begins. Modified Alternate Shot involves two tee shots, but only one second shot.
  • Why it matters: Chapman adds another layer of strategy and can sometimes save a hole if one player hits a poor initial drive but the other player executes an excellent recovery for their second shot.

Modified Alternate Shot vs. Scramble

A scramble is perhaps the most common team format in charity and social outings. In a two-person scramble, both players tee off, choose the best shot, and then both players hit their second shot from that spot. This process continues all the way to the green - best shot is chosen, both players hit from there, and so on.

  • Key Difference: In a scramble, you are never forced to play from a bad position after the ball is in play. You always hit from the best-chosen location. In Modified Alternate Shot, after the best drive is selected, the alternate shot sequence means you have to play the ball as it lies.
  • Why it matters: The true challenge of alternate shot golf - having to deal with the results of your partner’s swing - makes Greensomes a more demanding test of complete team play than a scramble.

The Winning Strategy for Modified Alternate Shot

This format is more than just hitting good shots, it’s about playing smart team golf. Here are a few coaching tips to help you and your partner score well.

1. The Best Drive Isn't Always the Longest Drive

When selecting which tee shot to play, don't automatically pick the one that's farthest down the fairway. You need to consider several factors:

  • The Lie: A ball in the first cut of rough with a clean lie is often better than a ball 15 yards farther that's sitting down, in a divot, or behind a tree.
  • The Angle: One ball might be on the "wrong" side of the fairway for an approach shot to a pin tucked behind a bunker. The shorter shot from the better angle is the smarter play.
  • Your Partner's Strengths: Does your partner love a 120-yard wedge shot? If you have two drives and one leaves them at 120 while the other leaves them at 90, choose the one that puts their favorite club in their hands.

2. Play to Your Partner’s Strengths and Aversions

Good teams talk constantly. Before you decide on a ball, have a quick chat. Say your drive is sitting perfectly but would require your partner to hit a long hybrid they despise. Your partner’s ball is 25 yards back, but the second shot would be with a 7-iron, which they hit with confidence. Taking the shorter drive is the clear choice.

By a similar token, if one of you is a wizard from the sand and the other struggles, this can influence your strategy. You might be more comfortable taking an aggressive line over a fairway bunker if the "miss" sets up the better bunker player for the next shot.

3. Think One Step Ahead

Great Modified Alternate Shot strategy involves thinking about the third shot, not just the second. On a par 5, for instance, you have two drives in play. Drive A is long but in the rough. Drive B is shorter but in the middle of the fairway.

If you take Drive A, your partner will have a difficult second shot from the rough just to advance the ball, likely leaving you with a long, awkward third shot. If you take Drive B, your partner can easily lay up to a great yardage, setting you up for a simple wedge into the green. Thinking about setting up your partner for success on the next shot is the hallmark of a smart team.

4. How Are Handicaps Calculated?

There isn’t a single, universally mandated rule for handicapping in a Greensomes event, and tournament organizers will set their own standards. However, a common method is to use a percentage of each partner’s course handicap. For example:

  • A popular formula: 60% of the lower-handicapped player’s course handicap + 40% of the higher-handicapped player’s course handicap.
  • Example: If Player A is a 10 handicap and Player B is a 20 handicap, their Greensomes handicap would be (10 x 0.6) + (20 x 0.4) = 6 + 8 = 14. Their team would get 14 strokes for the round.

Always be sure to check the specific rules of the competition you are playing in.
