Giants 9, Diamondbacks 8.
This comes immediately after I posted the the introduction to WPL, in which I pointed out that the median extra-inning game is a 99th-percentile nine-inning game. So naturally, the best game of an Opening Day that featured not one, but two extra-inning games, is a regulation affair.
It should be noted that it is virtually never a bad thing when a game of standard length surpasses the WPLs of multiple extra-inning outings, and this is no exception.

Measuring excitement: Introducing Win Path Length
What was the most exciting baseball game of last season?
Excitement is an inherently subjective quality, and as such,
this question has any number of possible answers. The most common choices would
likely be postseason contests, since they come with additional stakes; Game 3
of the World Series, a back-and-forth affair in which the winning run scored in
the ninth on an obstruction call, would be a popular selection, as would the
first game of the NLCS (which lasted 13 innings), the second game of the NLCS
(a 1-0 pitcher’s duel between Kershaw and Wacha), and the second game of the
ALCS (a Red Sox comeback on a David Ortiz grand slam).
If you expand the scope of the question to include the regular season, however, the question quickly becomes unmanageable. There are hundreds of extra-inning games to choose from,
and dozens of walkoff hits, and any number of astounding defensive plays or
surprising rallies or great individual performances that could qualify a game
for a particular list. So how does one go about sorting through all 2430
regular season games and picking the best?
With the caveat that any objective measurement of a
subjective quality is inherently flawed before it even begins, I have an idea
for an objective measurement of the subjective quality of excitement.

2014 MLB Predictions
This will (hopefully) be the least-analytical thing I post
here for quite a while. I could, of course, build a projection system and make
my picks that way, except for the fact that I’ve sworn never to build a
baseball projection system, for the following reasons:
1. Assembling a projection system would take a significant amount of time and effort. And since there are already systems out there that
are significantly more sophisticated than anything I would build, that time and effort would be a
prodigious waste, even moreso than the rest of my unpaid
work already is.
2. I would enjoy the sport less as a result. Whenever I make
predictions, I find myself rooting for them to come true instead of
hoping for entertaining or surprising things to happen. The primary rule of baseball
projection is “this guy will keep doing roughly what he has done before.” But one of the best parts of baseball is the fact that players don't always follow that rule. When the next Jose Bautista
or Chris Davis hits 50 homers or something, I don’t want to be the guy who
insists on predicting that this year’s breakout star is bound to regress to the
mean; I'd rather hang on and enjoy the experience while it lasts.
So my picks are generally made with as little study as I can
manage, which in turn allows me to slide by with minimal emotional investment
in them. It also ensures that they will turn out to be thoroughly incorrect –
but then, everyone else’s usually are as well.

Stopping the madness: A better way to score NCAA tournament brackets
Bracket season is upon us once again, which means that
millions of normally hardworking Americans will spend the next week carefully
examining an ordered list of 64 basketball teams and trying to select the
winners of the 63 games those teams will play. (Fine, it’s really 68 and 67,
but let’s not pretend that most people care overmuch about the opening-round
games, especially because most bracket pools ignore them.) Those picks will,
for the most part, be entered into online contests which will compare the predicted
brackets to the results of the games as they are played, and select the best
one as the winner. This should come as news to exactly nobody.
But for all the care put into the individual brackets by the
participants, the people running the contests generally put shockingly little
thought into the actual method used to evaluate them.

Upsetopsy: Garcia-Lopez over Nadal
It was September of 2010, and Rafael Nadal was on top of the
tennis world. Earlier in the month, he had won the US Open, thereby completing the
career Grand Slam, extending his streak of consecutive Slams won to three, and further
securing the top spot in the world rankings. The next event Nadal played was a
small tournament in Bangkok; he had a first-round bye and then won his next two
matches with ease (dropping 5 total service games in each one).
His semifinal opponent was fellow Spaniard Guillermo
Garcia-Lopez. He entered the tournament with an ATP ranking of 53 and a
respectable 21-19 record on the year, having lost in the first or second round
of all four Slams and with a solitary final in Eastbourne to his name. The three
wins that put him in the semis were all hard-fought, with scores of 6-4, 7-6;
7-5, 6-7, 7-5; and 7-6, 4-6, 6-3. And while all three came against top-75
opposition, none of them approached the level of the world’s best player,
one who had bested Garcia-Lopez with ease in their two previous encounters.

Rafa vs. Rafa
Rafael Nadal won three Grand Slams in 2010. Novak Djokovic
won three Grand Slams in 2011. That most basic method of tennis accounting would
hold those two years to be equal, but it’s not difficult to see why Melog 75 rates Djokovic's season higher; the Serb simply performed better in the other events.
It is significantly more surprising, however, that Melog
also holds Nadal’s own 2011 season, in which he won three tournaments and one
Slam, to be better than his 2010, in which he captured seven total titles including
the aforementioned three majors. 2011 is generally considered to have been a step back for
Nadal, with Djokovic seizing his place at the top of the heap.
So what is Melog thinking? There is a short answer for this,
and a long one. Let’s use the long one.

2010 Tennis Rankings: The top 10
With the last post having been the listing of the second ten from the 2010 tennis season, one might assume that the next one would be the top 10... and one would be right.
