Charts

NL CY Young contenders: Scherzer or Kershaw?

Today I want  to compare in a quick and simple way two of the best Aces in National League and sure 2017 Cy Young contenders: Max Scherzer and Clayton Kershaw.

IP Scherzer: 160.1

IP Kershaw: 141.1

Looking at their peripherals: (click to enlarge)

Scherzer is ahead on Strikeout percentage but Kershaw is better at concending Walks.  As the xFIP, the Dodgers’ ace is excellent.

Assuming xFIP is a better indicator than FIP, we can compare ERA and xFIP:


Both starters had a better ERA so far altough Scherzer’s span is longer and Kershaw’s xFip is slightly below 3.

Finally, we take a look at ERA- over the first four month.


Kershaw had a better April and an outstanding July, Scherzer did better in May and was amazing in June.

All Star Break: National League Division Race Charts

Since we are in the mid-season break, I have created charts that summarize how teams went the first part of the season. I have created graphs that draw the teams that have gained (or lost) games over or under .500.

This viz is not new. It has already been used by Espn until 2004 and by some users in the Edward Tufte blog. I consider it one of the graphics that best expresses  a good view of sports standings.

Ok,  now let’s enjoy the division races views from April to the All Star Break (National League, click to enlarge).

The goodnumbers Power Rankings

Espn or SI Power Rankings are an easy and quick way to read a recap of the MLB teams’ strenght. In this post I want to show you my Power Rankings way. I chose to use less words and more graphics to tell you how good or bad was your team.

Let’s starts with the win loss records (click to enlarge):


Red Sox and Dodgers are first in wins, good news from Cleveland and St Louis (8 wins).  Let’s take a look at the PCT:

No surprises from Houston and Los Angeles, Boston take the lead in AL EAST thanks to their .692 record, Giants show a sign of life and Yankees, Colorado and Rangers are suffering slumps.

Finally, the Runs Scorerd and Runs Allowed (click to enlarge).


Dodgers had an excellent pitching allowing only 30 runs. Cleveland showed a good offense and a strong pitching gaining an excellent run differential.

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.
