With many of the biggest names in the field already packing their bags in Memphis, a player who won already this year on Tour holds the top spot. Here's how things look at the halfway point of the FedEx St. Jude Classic, where Brooks Koepka leads by one shot:
Leaderboard: Brooks Koepka (-9), Austin Cook (-8), Steven Alker (-7), Russell Knox (-6), Chris Smith (-6), Scott Brown (-6), Greg Owen (-6), Fabian Gomez (-6)
What it means: Koepka began the round with a share of the lead, and while Alker briefly overtook him, the Kiwi closed bogey-double bogey to leave Koepka alone at the top.
