Home Run Derby is drawing 279x more Wikipedia traffic than normal

What this article is

The Home Run Derby, officially known as the T-Mobile Home Run Derby, is an annual home run hitting competition in Major League Baseball (MLB) customarily held the day before the MLB All-Star Game, which places the contest on a Monday in July. In the context of the competition a "home run" consists of hitting a baseball in fair territory out of the playing field on the fly. It differs from a home run hit during legal gameplay in that the batter is not competing against a pitcher and a defensive team attempting to make an out. In the Home Run Derby, all pitches are purposefully thrown slowly and at a closer range than the official 60 feet 6 inches (18.44 m) distance, usually by a coach behind a pitching screen. In addition, like batting practice, the batter remains in the batter's box after each swing and does not run, nor circle the bases to score a run. In 2023, Julio Rodríguez set the single-round home run record with 41 homers, topping Vladimir Guerrero Jr.'s 40 home runs in 2019.

How this was measured

Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
