Defending champion Davis Riley, who is playing the first two rounds with Scheffler, had two double bogeys on the front nine and shot 3-over 73 on the cozy course made famous by Ben Hogan, the only player to win Colonial in consecutive years (1946-47 and 1952-53). Riley is coming off a runner-up finish to Scheffler at the PGA.

The Charles Schwab Challenge begins Thursday at Colonial Country Club in Fort Worth, Texas. Split-tee action begins at 8 a.m. EDT. PGA Championship winner Scottie Scheffler and defending Schwab winner Davis Riley (along with Daniel Berger) go out at 1:45 p.m.

Tour rookie John Pak fired a 7-under 63 on Thursday and holds a three-shot lead after one round of the Charles Schwab Challenge at Fort Worth.

Scottie Scheffler held players currently playing in LIV Golf accountable with providing answers as to when the split between the two tours will end.

Since he keeps most of his emotions under wraps, those few moments when Scottie Scheffler lets loose seem almost unsettling.
