The Masters: Round 1 Notebook

• Justin Rose (4-under-par 68) holds the third 18-hole lead/co-lead of his Masters career in just his fourth start. In 2004, he opened with a 67 and led by two over Chris DiMarco and Jay Haas . He finished T22. Last year, a 69 matched Brett Wetterich for the 18-hole lead en route to a T5.

• Making his fifth career Masters start as a professional and sixth overall, Trevor Immelman posted just his second sub-par round (in 17 career rounds) at Augusta National, his other being a 7-under-par 65 in the third round in 2005 where he finished T5.

• Raymond Floyd (80) made his 44th consecutive start in the Masters while Ben Crenshaw (75) teed it up for the 37th consecutive year.

• Lee Westwood, who shared the lead at 4-under-par until closing bogeys on Nos. 17 and 18, led the field with seven birdies on Thursday.

• With two bogeys and an eagle on the day, Tiger Woods (72) has not broken par in the first round of the Masters since a 2-under-par 70 in 2002. Woods' first-round scoring average as a professional at the Masters is 72.50, contrasted with his final-round scoring average of 71.00.

• Ian Poulter posted the 19th hole-in-one in Masters history on Thursday at No. 16, the first ace since Trevor Immelman (Round 4, No. 16) in 2005. It was the 11th in tournament history at the 16th hole.

• All three of Zach Johnson's (70) wins have come in the state of Georgia -- the 2007 Masters Tournament along with the 2004 and 2007 AT&T Classic titles. In addition to his two titles in Georgia in 2007, Johnson flirted with a 59 (shooting a 60) at THE TOUR Championship at East Lake Golf Club in Atlanta and finished T2. Overall, Johnson made $2,896,500 of his $3,922,338 in official money on the PGA TOUR in the state of Georgia last year.

• The 1998 Masters champion Mark O'Meara, 51, birdied Amen Corner (Nos. 11-12-13) on Thursday en route to a 1-under-par 71.

• Johnson Wagner, winner of last week's Shell Houston Open and the last player to qualify for this week's field, posted an even-par 72. Wagner is trying to become only the sixth player (since WWII) to win the Masters after registering a victory the week before.

• Jack Nicklaus won his 14th major in his 56th start at the 1975 PGA Championship at the age of 35 years, 6 months, 20 days; Tiger Woods, currently with 13 major championships, will be 32 years, 3 months, 14 days this Sunday, April 13.
