Scott Piercy’s blister, Emiliano Grillo’s success on sixth hole among five takeaways from third round of 3M Open

Scott Piercy has a blister on his right foot, but it didn’t stop him from stretching his lead at the 3M Open to four strokes.

Piercy, who led by three at the start of the day, blistered the field with five straight birdies beginning at No. 3, and carded a 5-under 66 at TPC Twin Cities in Blaine, Minnesota, to build his lead over Argentina’s Emiliano Grillo.

Piercy began taking his shoe off between shots beginning at No. 9 and continued to do so for several holes.

“And people say golf isn’t a sport,” Max Homa tweeted of Piercy dealing with his blister. “Check mate haters!”

The 43-year-old Piercy held a commanding six-stroke lead until he made his lone blunder of the day at the last. From 248 yards, Piercy fatted his second shot at the par-5 18th into the lake fronting the green, but he recovered to salvage a bogey. It was still good enough to set the 3M Open 54-hole tournament record (18-under 195) as he seeks a fifth career PGA Tour title and first individual title since the 2015 Barbasol Championship.

It was a long day that began bright and early to try to beat forecasted storms. The weatherman was right and play was suspended at 10:57 a.m. Six hours and 38 minutes later, play resumed.

“It was a weird round, I feel like two rounds,” Tony Finau said. “You know, played the first eight this morning and then the final 10 this evening, so it was just kind of a strange feel to it when you have that long of a delay, but roll with the punches.”
