Tim Petrovic has been deadly accurate off the tee in the first three days, but he's struggling early in today's final round.
Petrovic missed two of his first three fairways but continues to hold steady at 13 under, two shots off the lead.
The fairways Petrovic missed on hole Nos. 1 and 3 were the first two he had missed on the front nine at Muirfield Village this week.
Through the first three rounds, Petrovic and Sean O'Hair led the field in fairways hit, with each player missing just four fairways. In the third round, Petrovid hit his first 13 greens until narrowly missing off the 18th tee in the first cut of rough.
Petrovic has been almost as accurate in greens hit in regulation, missing just 11 of 54 greens in the first three days. But he's missed two of his first five Sunday.
