TPI (Team Process Index)


Team Process Index is a calculation that is based on a team’s performance using key indicators that, in and of themselves, are very telling of a team’s chance to win. TPI is a new and innovative way to measure the things that matter most and actually calculate how your team plays, without taking into consideration wins/ losses. It uses many of the key concepts already mentioned in this book. It indicates how efficient a team has been during the game and will show strengths and weaknesses, not only in a single game, but also patterns throughout the season. It is based on process goals and all facets of the game (pitching, offense, fielding, and base running). TPI operates under the premise that if players consistently do certain things well, they will maximize their team’s TPI Score and also increase its chance to win the game in the long run.

It is much like the first time you beat a video game. You understand the game, you know what it takes to be successful, and now the real game begins—not only to beat the game, but also to earn the high score for the game. I like to think of it backwards for baseball. We want to earn the high score for TPI and if we can, the chances are that we will win the game, or at least be satisfied with our performance.

We all know that one of four things will happen once the first pitch is thrown:

1. You will play well and win.

2. You will play well and lose.

3. You will play poorly and win.

4. You will play poorly and lose.

Having a tool, such as TPI, to truly evaluate play regardless of wins and losses is a better way of creating an environment of improvement. It lets a team move past the simple happiness of a win to focus on finding things that need to be improved for the next game so that your team has an even better chance of victory. If you focus only on results, you can get lost in the thrill of victory and be satisfied with what may have been a sub-par performance. Using the Team Process Index prevents this. It creates a dynamic of constructive criticism that will encourage growth within any program at any level.

What Makes Up the TPI?

There are 10 Key Indicators:

1. Error Differential
2. Walks/HBP Differential 3. Strikeout Differential
4. Stolen Base Differential

The B.A.S.E.2. System makes up indicators 5 thru 9:

5. Big Inning
6. Answer Back
7. Score First
8. Extend the Lead
9. Score with 2 Outs
10. The Quality At-Bat System

These criteria have been selected because they are measures of efficiency in all facets—pitching, defense, base running, and offense—of the game.

B.A.S.E.2. is a great indicator, in and of itself. Since the implementation of the B.A.S.E.2. System, our team has been 220-6 when we have recorded three of the five categories in B.A.S.E.2.

QAB is a great indicator, too. Since we began measuring our QAB % for each game, we have been 235-10-2 when we are above 60%, while only 50-25-4 when having a QAB % under 60%.

The bad parts about using only the QAB/B.A.S.E.2. Systems are that they are completely offensive. We (Jon Fitzpatrick and I) wanted to come up with something more comprehensive, multi-faceted, and also more reliable than just B.A.S.E.2. and QAB. Even though those systems are great, TPI is better.

How To Calculate TPI?

After looking at past seasons, on the data we have collected thus far, we found that a TPI above 48 points predicted a winning outcome 98.4% (126-2) of the time. The best part is that we did not factor our 88-game winning streak into the calculations. We wanted it to stand alone without those games inflating the overall numbers. On the other end of things, when teams were below 48 points, their winning percentage was just above .500. Again, we are not after the wins. I am most concerned with what do we need to do well to give ourselves the best chance for a win— the process. The point is, if you do these things correctly, then success may come your way. Winning is a byproduct of working this process. TPI can be a way to focus your entire program and communicate team philosophy. Especially at the end of games, going over the different parts of TPI helps re-emphasize the things your team did well that night and the areas of growth.

Each category is given a point value in the TPI system. You would receive positive points for the differentials of the four following areas: Errors, Walks/HBP, Strikeouts, and Stolen Bases.

As mentioned in the Freebie War section of the book, you would be plus 3 if you had one error and the other team had four. You would be minus 2 points if the other team earned six walks/HBP and we only had four. If we struck out 7 times and the other team struck out 7 times, then we would not earn any additional points toward our TPI Score. If we had a total of five stolen bases and did not allow the other team to swipe a bag, then we would earn 5 additional points in the Freebie category of TPI. These points will be either added or subtracted from your points earned within B.A.S.E.2. and the QAB Percentage.

If you fulfill a certain category within B.A.S.E.2., then your team scores 10 points for each. For example, top of first your team scores three runs. Your team would just earn 10 points for Scoring First and 10 points for having a Big Inning. Let’s say that one run was scored with 2 outs, then you would get another 10 points. You cannot score more points if you have another Big Inning, or any of the others previously recorded. The most you could ever score off of B.A.S.E.2. is a total of 50 points. Remember that 48 is the benchmark to beat. So, if you had all of the possible points for B.A.S.E.2., then it would be your team’s responsibility to keep your team’s overall TPI Score above 48 by making sure it does the other things right, like hold runners, play good defense, etc. Because if they do not, they run the risk of letting their TPI drop below the 48 mark.

The last way to earn points toward the team’s TPI is multiplying by 10 the team’s QAB Percentage at the end of the game. Example: the team has a 55% Quality At-Bat Average; times that by ten, it would earn an extra 5.5 points toward the total. If calculating TPI sounds too confusing, we have created an easy- to-use worksheet for coaches to use.

Example of a Team’s TPI Score

Freebie War:

Errors – Us = 3, Them = 5, Result +2 for us

Walks/HBP given up – Us = 5, Them = 9, Result + 4 for us

Stolen Bases – Us = 4, Them = 0, Result +4 for us

Strikeouts – Us = 3, Them = 6, Result +3 for us

Total Point from Freebies = +11 for us


If the team has a Big Inning, Scores First, Extends the Lead, and Scores with Two Outs, it would earn another +40 points for its overall TPI Score.

Quality At-Bat Percentage

If the team goes 22 for 33 during the course of the game, this is a 66.7% clip. This is a great average. As it pertains to TPI, you would multiply the decimal .667 x 10, which equals 6.67. This is the final piece to the overall TPI Score.


+11 (From Freebies) +40 (From B.A.S.E.2.) + 6.67 (From QAB) = 57.7 TPI Points

This score alone would lead me to believe they won the game based on previous findings. Even if they did not, what a coachable moment it would be to know you played well, had a great TPI Score, and coach your team up.

The analysis is so easy that it can be done as you look over the scorebook in just a few minutes after each game. These data can be used to debrief your team after a game, which most coaches already do. You can now make this meeting more productive and go over facts, rather than rant about your feelings, and how play was “poor” or “great.” Would it not make more sense to tell your team the specific things they either did, or did not do, that contributed to the game’s outcome? I am not insulting any coach’s intelligence by saying that individual players are not going to know overall what went well during the course of the game. TPI gives teams a much more systematic, fact-driven way of reacting to their performance. The numbers do not lie. Praise

your team when its TPI is high, or they have set a season record. Give them positive, constructive criticism when things do not go well with TPI, as well.


Start now! Why not use TPI? Remember: This not a way to gain more wins. It is a way to provide feedback to players and coaches. Such constructive criticism will help you continue to make strides in becoming the best. Let the data drive your decisions, rather than using subjective feelings that often get in the way. Stay focused on the process and not the end result with TPI.
