Jordan Spieth held a one-stroke lead after day two of the Charles Schwab Challenge in Fort Worth, Texas.
The Texan, who won at Colonial Country Club in 2016, shot a four-under 66 to follow his superb 63 on day one to be at 11-under for the tournament, a shot ahead of compatriot Jason Kokrak after his second straight 65.
Sergio Garcia, co-leader after round one, shot a 69 to share third place at eight-under with Colombia’s Sebastian Munoz and American Patton Kizzire.
Justin Rose was the top-placed Briton but drifted to seven shots off the lead after a second successive 68, featuring three birdies and a bogey, while fellow Englishman Ian Poulter was two shots further astern on two-under.
Spieth played another strong round, birdying three of his first six holes and picking up another shot on the 14th in his second straight bogey-free day.
England’s Lee Westwood improved on a 75 with a 69 but still missed the cut, as did compatriot Tom Lewis and Northern Ireland’s Graeme McDowell.
