0 Games. Zero Clues. One Mission.
The Daily Whiff is my classroom. Every morning it gives me last night’s baseball in numbers, and one new idea to understand. I’m learning the stats, the strategy and the stories that define the diamond, and you’re welcome to learn along with me.
What you’ll find here
- Daily: every morning. Last night’s scores, the most dramatic game told through its win-probability swings, the best performances, the playoff race math, tonight’s games in European time, and scores from Korea and the winter leagues.
- Stat Lab: in every Daily. One advanced stat (FIP, WPA, wRC+ and more), explained with the real numbers of a player from last night.
- Sunday Slugfest: every Sunday. The whole week in numbers.
How this site works
The Daily is assembled automatically each morning by my own software. It downloads official data, calculates what mattered (which game was the most dramatic, who helped their team win the most, what each team needs to clinch), and lays it out in tables. No text is invented and no AI writes the posts. Headlines from other outlets appear only as links to the original stories. I can step in and edit any post by hand, and the software will never overwrite my changes.
Sources
Game data comes from MLB Advanced Media (the MLB Stats API and Baseball Savant) and MyKBO Stats. The Daily Whiff is an independent, non-commercial fan site, not affiliated with Major League Baseball or any club.
Grab some peanuts and Cracker Jack, and let’s figure this game out together.
Data and method
Scores, play-by-play and Statcast numbers come from MLB Advanced Media (the MLB Stats API and Baseball Savant). We publish them as facts, figures and our own calculations, never MLB’s text, images or video, and the site carries no ads; results from Korea come from MyKBO Stats. The Daily Whiff is an independent, non-commercial fan site, not affiliated with Major League Baseball or its clubs.
Baseball history comes from Retrosheet’s play-by-play files. The information used here was obtained free of charge from and is copyrighted by Retrosheet. Interested parties may contact Retrosheet at “www.retrosheet.org”.
Who is elected to the Hall of Fame comes from the MLB Stats API; the share of the vote that elected a writers’ pick comes from Wikipedia’s article on that year’s balloting (CC BY-SA). We use only those numbers, never the article’s text, and a post that prints them credits Wikipedia and links the article.
Our own win expectancy starts from Retrosheet’s regular seasons 2015–2019 and 2021–2025, leaving out the shortened 2020 season. From those games we count how many runs a team goes on to score in the rest of an inning from each combination of outs and runners on base. We then follow the rest of the game inning by inning to get the home team’s chance of winning from every inning, score and base-out state.
No home-field bonus is added by hand: the home team’s edge comes out of the data. The charts of the Daily’s own games use the win probability MLB publishes; our table powers the comparisons with baseball history.
