MEMPHIS, Tenn. (AP) -- Brooks Koepka is tuning up quite nicely for the U.S. Open at the event he added at the deadline.
Koepka, who had a share of the lead after the first round, shot a 3-under 67 Friday to lead the St. Jude Classic by a stroke after 36 holes. He turned in a four birdie-one bogey round for a 9-under 131.
Fellow American Austin Cook (64) was at 132.
Steve Alker briefly had the lead at 10 under with two holes to play only to finish bogey-double bogey.
