Hi all, I’m Ivan Lukianchuk, the CTO and co-founder of RunPlusMinus™️and this is our weekly report about performances of Major League Baseball players and teams.

For last week’s report (week 16), click here.

The RPM Report gives you a unique insight into on-field performances based on the new RunPlusMinus™️ statistic. For more information about this statistic, please go here.

Wondering how we differ from WAR? Read this.

TL;DR — We’ve built a new baseball statistic that allows us to rate all of the players (pitchers, batters, runners, fielders) on the same scale: performance.

This report has two parts:

  1. The week’s best performers (week 17 — July 16th through July 22nd)
  2. All regular season data up to and including July 22nd 2018.

Some new changes with this week’s report: we’ve taken out most overpaid and we’ve implemented Park Effect into our calculations, so a few players have had some minor adjustments, but overall most player rankings have stayed the same.


The Best Players of the Week

We’ve reported the top 10 best pitchers and batters of the week. There are separate rankings for starting and relief pitchers.

Players are ranked on the RPM statistic. A total above zero means above average performance for the pitcher or batter. The RPMs in the report have been multiplied by 100 to make it easier to read and compare. The higher the number, the more value and impact that player brought to their team in their role as a pitcher or batter.

In each top 10 list we show how many times a player has made it into a weekly top 10 list, with 1 meaning this is their first.

The Top 10 Starting Pitchers (week 17)

Chris sale tops the weekly chart and makes his 4th appearance in the top 10s, he is also a frequenter of the top 25 chart. We’ve got 4 returning pitchers this week, which is on the high end of repeats, and we’ve got Verlander, another pitcher whose seen the top 25 a number of times make his 3rd appearance.

We’ve got a range double the size of last week at just over 6 RPMs!

The lowest starting pitcher RPM total of the week was -31.4 RPMs.

The Top 10 Relief Pitchers (week 17)

Not all relief pitcher situations (outs and bases-occupied) are equal threats. Furthermore, relief pitchers generally face fewer batters that starters. Relief pitcher ratings exclude pitchers with fewer than 3 batters faced.

Last week was all new players, but this week we see three returning faces, each with their second time on the charts. A massive range of roughly 20 RPMs separates top from bottom and the same amount separates 1st from 2nd as 2nd from 10th!

For reference, the lowest Relief Pitcher RPM value this week was -155.4. This is by far the largest we’ve seen, usually it’s under 100!

The Top 10 Batters (week 17)

Another three returners this week, each only back for their second time. Carpenter and Judge are both in the top 25 this week. Last week’s RPM range was cut nearly in half this time to just over 3.

The lowest RPM for a batter in week 6 was -42.8.


The State of the Game so Far

We’ve looked at last week, but let’s take a look at the entire season so far up to the 23rd of July.

We’ve got a number of interesting charts ranging from top players, team rankings and most overpaid players.

Top 25 Players to July 23rd

Mike Trout still in second as last week he fell to Jose Ramirez, but now he’s getting quite close for a comeback. Betts still in 3rd and Martinez still in 4th. Judge and Suarez trade places, while Arenado jumps 3 spots. A lot of minor shifting around, but mostly the same people are on this list.

Verlander is back and Bauer is out, while Sale is still the top pitcher on this list.

Things to note: a “rating of 0” is always the average over all active players, with positive values representing above average performance and negative values below average performance. Earned salary is how much of the team’s total salary did that player’s performance justify. Bolded payroll earned means a player is worth more than they are paid (in the context of their own team), and italicized and red means they aren’t. Blank ratings mean the player did not meet a minimum level of participation to be ranked on a specific component.

Where Are They Now? 2017 Top 25 to 2018

2017 brought us over 48 million data points and from that we derived the top 25 player list. How do those players rate in 2018? Below is a chart showing where each player stands today. Note that only 10 players (ranks highlighted in yellow) are still in the top 25! The rankings will change as the season moves forward.

Votto falls 5 spots, Schoop improves by about 90, Andrus by 200, Abreu by 80, and everyone else is nearly the same.

This week we hold steady at 10 players back in the top 25.

Team Rankings as of July 23rd

As the season continues past the half way point, there aren’t a lot of huge changes anywhere except for Cincinnati taking a 4 rank slide down to rank 19. Boston’s hold over Houston is around the same as last week.

Until next time…

Stay tuned for our future reports due out every week this season. If you want to be reminded whenever we release new content, please subscribe to our mailing list to be kept up to date!
