Player marking own card | Golf Monthly
Players Must Be Accompanied by a Marker for the Entire Round
The purpose of a marker is to certify that a player's score for each hole is correctly shown on the player's scorecard. If a marker is not with the player for the entire round, the scorecard cannot be properly certified.
For example, if a player plays several holes without his or her marker and the marker enters the player's scores for the holes the player played alone, the scorecard cannot be properly certified under Rule 3.3b.
The player should have insisted that the marker accompany the player for all of the holes. If the marker was unable to do so, the player should have asked another person to serve as his or her marker. If that was not possible, the player was required to stop play and report to the Committee so that another marker could be assigned.
In medal she would be disqualified and it looks to me that in stableford she would also be disqualified since a breach of 3.3b is not one of the breaches listed as only resulting in zero points. 21.c(2)
