James Hahn posted his second 6-under 64 of the tournament on Saturday at TPC Four Seasons, and will take a one shot lead into Sunday’s final round at the AT&T Byron Nelson.

Hahn is at 12-under 198.

Former FedEx Cup champion, Billy Horschel (-11), is alone in second, after firing a 4-under 66 – his third consecutive sub-70 round.

Jason Day made the move of the day. The former World No. 1 carded a 7-under 63, and is at 10-under, good for T3.

Current World No. 1, Dustin Johnson, finished at 1-over on Saturday, and is at 5-under for the tournament. DJ will need a lot of help on Sunday to grab title number four of the 2017 season.
