Jordan Spieth’s unfortunate display at the 12th hole at Augusta National last year has led to at least one happy development: a top-notch win probability calculator.

Dan Rosenheck, data editor at The Economist, was inspired to develop Economist Advantage in Golf Likelihood Estimator (EAGLE) after seeing Spieth’s collapse and asking the question: “Was this the worst collapse in major golf history?”

An interesting sidebar: It wasn’t. And while you ponder the worst collapse in recent major golf history, some more details on the EAGLE.

According to Golfweek’s David Dusek, the tool is built from a “dataset of more than 457,753 holes played by golfers in the Masters, U.S. Open, British Open and PGA Championship and almost one million rounds played in tournaments that award world ranking points.”

The EAGLE determines a player’s likely score on a hole based on a player’s OWGR-derived ability, a hole’s par and its length. The utility then simulates the golfer’s play on that hole and all remaining holes…10,000 times (as well as every other golfer’s remaining holes). The number of times a golfer wins in the simulation out of 10,000 attempts equates to his win probability.

Per EAGLE, after Jordan Spieth bogeyed the 10th and 11th holes at ANGC last year, he still had a 96 percent chance of winning the Masters. After the seven at the 12th hole his chance of winning fell to 23 percent.

As mentioned, The Economist found that Spieth’s collapse was not the worst in major championship history. Don’t worry, Jean van de Velde, it’s Adam Scott’s 2012 British Open blowup that’s the recipient of the inglorious honor. Four-up with four holes to play, Scott’s win probability was 98.6 percent.
