Pace of Play

Different

USGA

First bad time: warning; Second bad time: one-stroke penalty; Third bad time: two-stroke penalty (additional)

PGA TOUR

The PGA TOUR enforces a Pace of Play Policy. Groups are expected to keep position on the course; a group out of position may be put "on the clock."; When a group is being timed, each player is allotted a maximum time to play a stroke (with an extra allowance for the first to play). Exceeding the ...

Section 2: Equipment

Different

USGA

USGA championships apply the One-Ball Rule: during a stipulated round, the player must use a ball of the same brand and model. The penalty for breach is, in stroke play, two strokes per hole at which any breach occurred (with a maximum penalty of four strokes per round).

PGA TOUR

The PGA TOUR Anti-Doping Program prohibits listed performance-enhancing substances and methods. Players are responsible for what is in their bodies and may be tested in and out of competition; the program is part of the integrity framework that surrounds equipment and play.

Section 3: Playing Area

Different

USGA

Out of bounds is defined by the line between the course-side points of white stakes and fence posts at ground level. Where stakes and a fence are used together, the inside-edge-of-fence definition takes precedence at the discretion of the Committee.

PGA TOUR

A PGA TOUR event is contested over an 18-hole golf course, almost always set up to a par of 70, 71, or 72. Total yardage for a TOUR set-up commonly falls in the range of roughly 7,100 to 7,600 yards, varying by course, elevation, and conditions.

Section 5: Rules of Play

Different

USGA

The USGA enforces a pace-of-play policy designed to keep play moving and to penalize unreasonable delay. The policy works as follows: Stroke play: most USGA championships (U.S. Open, U.S. Women's Open, U.S. Senior Open) use 72-hole stroke play over 4 rounds; Match play: U.S. Amateur, U.S. Women's...

PGA TOUR

Section 6: Scoring

Different

USGA

From 2018 onward, the U.S. Open playoff format is a two-hole aggregate playoff followed by sudden death: The player who completes the stipulated round in the fewest strokes wins; 72-hole total (4 × 18 holes) determines the championship in stroke-play events; A cut is applied after 36 holes in U.S...

PGA TOUR

The score for each hole is the number of strokes taken plus any penalty strokes; the round score is the total for 18 holes, and the championship score is the total for all rounds played.; Scores are commonly expressed relative to par (for example, "10 under par").; In stroke play, a marker (typic...

Section 8: Safety Considerations

Different

USGA

The three-tone air horn signals immediate suspension of play, typically for lightning. Players must stop play immediately, drop the ball as it lies (or mark with a small marker), and proceed to designated shelter.

PGA TOUR

The competition committee monitors weather, particularly lightning, throughout tournament week using on-site meteorology.; When a dangerous situation exists, the committee sounds the immediate-suspension signal and players must stop play at once, even mid-hole. A separate signal is used for a nor...
