The win-loss sparklines

These days I have worked on the win-loss sparklines for each Mlb team based on their 2017 results. The win-loss sparklines are not new, it were introduced by Edward Tufte (a dataviz guru) and some sports sites (e.g. Baseball Reference, ESPN or The Hardball Times) use or have used it.

What makes good the win-loss is that it suits perfectly working on binary data. With the win-loss information it’s easy to track an MLB season results.

Let’s take the St Louis 2017 record up to May 20.


Symbol meanings:
Upward column = wins
downward column = losses
horizontal line = home game
no line = road game
| red = win or loss by 3 runs plus

And now here are the win loss sparklines (designed in the Tufte’s style) tracking the teams results up to May 20. Games postponed are not counted.

Cardinals 2017: shadows and lights


With nearly a quarter of season complete, the Cardinals are on track to battle for the first place in the the NL Central. The rotation shined thanks to the performances of Leake, Wacha and Lynn. They lifted up the team to the top of the division. But after they lost the last 3 games, the biggest concerns of this 2017 continue: defense, baserunning and bullpen.

Waiting for David Price


Price is expected to return in late May, after his elbow soreness. His addition will be good for the Red Sox that are trailing the Yankees and the Orioles. Apart from Sale and Rodriguez, the Red Sox struggled on the mound and Price could be the right boost to their starting rotation.
