POTOMAC, Md. (AP) — Jason Day shot a 7-under 63 to take the first-round lead at the Wells Fargo Championship.
Day has been tinkering with his swing in an effort to end a four-year victory drought on the PGA Tour.
Joel Dahmen was a shot back on what could be the best day for scoring at TPC Potomac at Avenel Farm, with rain, wind and unseasonably cool temperatures in the forecast through Sunday.
Matthew Wolff, local favorite Denny McCarthy and PGA Tour rookies Aaron Rai, Callum Tarren and Paul Barjon are two shots back.
