Jordan Spieth has completed his second round at the AT&T Byron Nelson with a share of the lead.

Spieth shot a 5-under 65 on Friday to get to 11 under after his round. He was tied with Brooks Koepka, who shot a second-round 64.

First-round co-leader Sergio Garcia was among those playing afternoon rounds at TPC Four Seasons.

This is only Spieth's second tournament since blowing a five-stroke lead on the back nine at the Masters while trying to win at Augusta for the second year in a row. The world's No. 2-ranked player missed the cut last week at The Players Championship.

Spieth's only bogey Friday was a three-putt at the par-3 13th, the same as in his opening 64.
