TPS Primer

By now, you have seen these three letters “TPS” being referenced along side pitchers stats. TPS stands for Total Performance Score and has nothing to do with Lumberghs’ anal reporting system from the movie Office Space. As I stated in an earlier post, it wasnt until I was explaining my system to Marc when those letters rolled off the tongue….I hestiated and said ….Shit!, thats from that movie! A movie that I watch everytime when Im trolling through the channels….an under the radar classic!

TPS was born when I first started ranking NL pitcher performances after the 2009 season. The 1st generation numbers were very simplistic. They did the job but I wasn’t hitting the mark in projecting breakouts for the following season. So before the 2011 season started, I set out to create a complex stat formula to enhance my current system. This was because of the frustration of breaking down and comparing all the different stats and pherphials from multiple sites. If your familar with the “Game Score” measure, then look at the TPS as a pitchers overall season score, but not tabulated the same way. Overall, the TPS encompasses numerous stats and pherphials and they are squeezed through eight differents equations that creates the TPS number. After several different versions, I settled on a final product just prior to the end of the 2012 season. Once I had began to push the stats through the formula from 2012, I was shocked with the initial results just after completing a few NL teams and then stunned with the ease of making the breakout picks for 2013 season. The TPS has a small equation included, in an attempt to forecast a pitchers future performance. I know that this as true as the Punxsutawney Groundhog predicting the coming of the Spring season, but I will continue to tweak this equation until I can build some consistency on the pitchers I select and their overall season’s performances.

When the TSP is implemented at the end of the season and I begin to rank the pitchers, you can use the TPS number to actually place them into tiers. Here’s how those numbers breakdown in regards to Starters vs. Relievers:

SP TPS Grading System
.000 to .075 – A Tier 
.076 to .125 – B Tier
.126 to .175 – C Tier
.176 & Higher – D Tier

RP TPS Grading System
.000 to .050 – A Tier

.051 to .075 – B Tier
.076 to .100 – C Tier
.101 & Higher – D Tier

All pitchers stats are sent through the same formula. The differential in the numbers are because relief pitchers don’t rack-up the innings that a starter would, and thus causes a somewhat lower TPS than starters, but not really that much, as you can see. I can achieve a TPS number for a pitcher at any time throughout the season and I will begin to include them in my daily performance posts as the season progresses.

So as you begin to see the TPS appearing with pitchers stats, please come back and use the above grading system as guide.

5/12/14 Addendum

When I set out to create the TPS formula I wanted it to be a dynamic stat. With that, if any changes were made, I wanted the number to stay true. Meaning, I didn’t want to go back through 5 years of pitchers and upset their TPS scores, based on any changes. Today I created a new TPS designation for when a pitcher has split stats as a starter and in relief. They are as follows:

cSR\TPS – Total Performance Score for combined stats as a SP and RP.

SP\TPS – A split Total Performance Score for pitchers used in a dual-role (SP/RP), but as a Starting Pitcher

RP\TPS -A split Total Performance Score for pitchers used in a dual-role (SP/RP), but as a Relief Pitcher

These designations will be incorporated into the daily performances mentions when practical.
