Rock finished T-7 at this year's British Open.
KILLARNEY, Ireland (AP) -- Robert Rock of England has been disqualified from the Irish Open for making a mistake on his scorecard after shooting a 6-under 65 in the first round.
Checking through his card after the round Thursday, tournament officials discovered that Rock had transposed his scores on the 14th and 15th holes at the Killarney Golf and Fishing Club.
He had signed for a 4 and a 3 when he had taken a 3 and a 4.
Tournament director David Probyn said that although the total was right "the hole scores he signed for were wrong so he was disqualified."
In the 2009 Irish Open at County Louth, the 33-year-old Rock reached a playoff only to lose to Irish amateur Shane Lowry.
