Handicap Index has been reduced due to Exceptional Tournament Performance as defined under Section 10-3 of the USGA Handicap System Manual .

This calculation uses all the tournament scores played within the last 12 months or within your last 20-score history regardless of date played. These are called eligible tournament scores and there must be at least 2 eligible tournament scores to continue this calculation.

No eligible tournament scores are posted. The handicap index is not subject to T-Reduction.
