McIlroy dominant once again

Rory McIlroy did it again. And he now stands alone for his dominant performance.

McIlroy won the PGA Championship for his fourth major victory. Here are some of the statistical highlights.

• He is a combined 62-under par over the course of those four victories. That is the lowest cumulative score to par through a player's first four major wins among the 28 who have won at least four.

Beginning of the Rory Era?
Most Major Wins Since 2008 U.S. Open

McIlroy became the fourth-youngest player to win his fourth career major. At age 25, 3 months old, he trails only Young Tom Morris (21 in 1872), Tiger Woods (24 in 2000) and Jack Nicklaus (25, 2 months in 1965).

• McIlroy is the fourth player to win a major while ranked No. 1 in the World Golf Rankings, joining Woods (11 times), Fred Couples and Ian Woosnam (one each).

• He’s the first player since Woods (2007-2008) to win three straight starts on the PGA Tour.

• McIlroy becomes the first player since Padraig Harrington (2008) to win back-to-back majors (Harrington also won Open Championship & PGA Championship).

• McIlroy joined Woods and Sam Snead as the only golfers to go from three to four wins in the next major in which they played.

• He’s one of six players to win consecutive majors at age 25 or younger, joining Morris, Woods, Bobby Jones, Gene Sarazen and J.H. Taylor.

• McIlroy won with length off the tee. He covered 63 percent of the yards of the par 4s and 5s with his tee shots, the highest percentage in the field. He averaged a field-best 3.8 on the par 4s.

McIlroy also putted well. His 37 one-putts tied for fourth-most in the field.
