Scottsdale, AZ (Sports Network) - Defending champion Jay Don Blake fired a 6- under-par 64 on Thursday to grab the lead after one round of the Charles Schwab Cup Championship.

Gary Hallberg is one stroke back in second place, while Fred Couples, Jay Haas, Bill Glasson and Olin Browne shot 4-under at the Cochise Course at Desert Mountain Club to share third.

The top 30 players are in the field for this event -- the final regular-season tournament of the season, which will not only produce the Player of the Year, but also the money title winner and the $1 million annuity for capturing the Charles Schwab Cup.

Bernhard Langer, who leads the both the race for the Charles Schwab Cup and the money title, overcame a slow start and birdied three out of his last four holes on Thursday to finish tied for 14th place at 1-under.

The German Langer is 211 points ahead of Tom Lehman and 657 points in front of Roger Chapman in the race for the Charles Schwab Cup, and only those three players can capture the Cup with double points awarded this week.

Lehman, who won the race for the Charles Schwab Cup and the money title a season ago, carded a 68, while Chapman shot 69.
