Objective player performance scoring

This topic comes to the surface at various times during the year. Most often around district and club selection times. If you are a serious bowler striving for selection in club or district teams, you have probably asked yourself "What are the selectors basing their selections on?".

Oddly enough, team selections are commonly based only on subjective analysis of previous performances, reputation, casual observation, here-say and rumor. On rare occasions results from the 40-bowl test or similar are also employed. But this test and other similar tests provide little insight into a bowler’s actual performance during a game or their cumulative game performances over time. For a sport that is very easy to objectively score a player’s performance, selectors continue to favor subjective methods to choose players and teams.

In simple terms, this is a proposal for a system to rate bowler's performance purely on each bowl delivered during a game. Theses "performance scores" can be used to compare performances on the day and over time on different surfaces, different positions and different situations.

A fine-tuned system like the following could be used globally to rate player performance, compare player performance, compare performance through time and aid with team selection.

Not excluding the mental skills and qualities bowlers need, such a scoring system proposes that a player’s performance can be measured by scoring each delivery. As a target sport, "how close to the target" is the obvious and easiest way to rate a delivery. Seen often, is the over rating of one-off magic shots (with magic results), distracting from overall “performance” of a player, sometimes over-shadowing reasonable performances of other players. They say, "you are only as good as your last bowl". A system like the following scores every bowl.

After all deliveries are scored an average can be calculated for each player in a game. As a benchmark for high performance, an average of 3.0 is equivalent to drawing within a mat of the target with each bowl played.

This system is not intend to detract from qualities like “desire to win”, “ability to play under pressure”, “good communication”, “playing the right shot at the right time”, “reading the head and calling the right shot”, “understanding your own team and opposition and playing to strengths and weaknesses accordingly” or a skips ability to stay in a match even when his team is struggling.

This is only a starting point and constructive discussion or any thoughts on this would be greatly appreciated.

DETAILED LAWN BOWLS OBJECTIVE SCORING SYSTEM (K1)
Designed for Fours play but suitable for others.
Rate and record score for each bowl played

(Once familiar, leads or seconds can record these scores with assistance from team mates or a dedicated score team can be employed, 2 preferred)

  • Focus should be on the accuracy of the delivery rather than the scoring success.
  • Use figure (1) below as a guide.
  • Bowls shorter than a mat are rarely in the count and should be scored accordingly (0).
  • The situation and intention of a delivery should be considered when scoring.
  • The value of shots through the head will vary in different situations.
  • Bowls entering the ditch will often deserve zero points.
  • Penalties intended only for high performance teams.


Select highest score available for each delivery from table below:

Delivered Bowl Description Score
A1 Draw behind with some chance of getting shot 1
A2 Draw within a metre of target (behind) 2
A3 Draw within a mat of target 3
A4 Draw within mat width of target 4
