BLAINE, Minn. — PGA Tour officials moved Saturday's final tee times up to 8:50 a.m. because of forecasted severe weather on the plain in Blaine, which gives 3M Open second-round leader Scott Piercy four fewer hours to contemplate his three-shot advantage.
After changing his swing coach, his caddie, his putter and driver the past two weeks, Piercy followed Thursday's 7-under-par 65 by doing it one better. His Friday 64 is two shots off the tournament record 62 he set the first day of the inaugural 3M Open in 2019.
It also leads Argentina's Emiliano Grillo by three shots, England's Callum Tarren by five and five others — world 17th-ranked Tony Finau, Thursday's co-leader Sangjae Im, Fargo's Tom Hoge, Robert Streb and Doug Ghim — by six.
