Shane Lowry had surged into contention at the Open Championship after back-to-back eagles on par fours.
Lowry cut a frustrated figure over the opening two rounds at St Andrews as his four-under-par total after 36 holes was enough to make the cut but saw him nine shots behind leader Cameron Smith.
The 2019 champion started slowly on a day of low-scoring on the Old Course, but his round came alive on the ninth hole.
