In a move to enhance competitiveness and viewer engagement, TGL, the innovative indoor golf league founded by Rory McIlroy and Tiger Woods, has revised its "Hammer" rule mid-season.

Each team will have three Hammers to use at their discretion, but only once per hole. The maximum a hole can be worth is three points.

TGL is changing the rules around how the hammer is used and how often it can be used in a match, responding to game results that show the points-elevating concept isn't being used as often as they had hoped.
