Southern Hills' reputation for providing the hottest environment for the players is well-earned. Of the 10 courses that have hosted multiple PGA Championships, the track in Tulsa has the highest daily high temperature in August at 93. It's already looking like the weather this week will make 93 look pleasant.

The early forecast is for sunny skies, and just a 10 percent chance of rain all four tournament days, with a high of 100 on Thursday, but a nice cooldown to 92 by Sunday. It could be worse: the average daily high in Tulsa in July is a degree higher at 94.

The average highs for August for those 10 courses:

Course ... Average high temperature
Southern Hills ... 93
Shoal Creek ... 90
Atlanta Athletic Club ... 88
Valhalla ... 86
Riviera ... 85
Inverness ... 84
Medinah ... 83
Oakland Hills ... 82
Firestone ... 80
Oak Hill ... 79

With Seve Ballesteros officially retiring from golf on Monday, we asked Golf Digest resident historian Cliff Schrock to give us the five most memorable shots (and there were many to choose from) of Seve's career:

1. 1984 British Open at St. Andrews: Curls in a 15-foot birdie putt on 18 in the final round (photo) to win over Tom Watson and Bernhard Langer.

2. 1983 Ryder Cup at PGA National: His 240-yard 3-wood second shot from a bunker to the fringe on the par-5 18th in singles vs. Fuzzy Zoeller halves the match, but Europe narrowly loses the cup. U.S. captain Jack Nicklaus called that 3-wood the greatest shot he'd ever seen.

3. 1976 British Open at Birkdale: On the par-5 18th, Seve runs a 9-iron chip shot between two bunkers to 4 feet to secure second behind Johnny Miller and makes a big impression in his first major international exposure.

4. 1979 British Open at Royal Lytham & St. Annes: On the 16th hole, he deliberately drives his ball into a parking lot, gets a free drop, and hits sand wedge to 18 feet and makes the putt for birdie en route to victory.

5. 1983 Suntory World Match Play Championship at Wentworth: On par-5 18th, one down to Arnold Palmer in the opening round, he chips in from 50 yards for eagle with an 8-iron and then beats Arnie in 21 holes.
