Over the past few years, I've contributed to/developed my own rosters for the NBA 2k series, as well as the EA NHL series (NHL Revamped), but MLB The Show has become my favorite series by far.

While playing MLB 17, I started thinking about making a roster for the series. I worked on developing a ratings calculator, from scratch, and started testing in-game, while basing ratings on The Show's sim engine.

This year, I have released my work for all to enjoy. It includes re-rates of all MLB players based on data collected from Baseball Reference and FanGraphs. A weighted average has been used, based on 3 years of data (when possible).

If fewer than 3 years of data are used, as many as possible will be used, and regression is applied.

For rookies on MLB rosters, or for players who are on MLB rosters who were inactive last year, projections (Marcel/Steamer/ZiPS) are used

Full pitch edits are included using Brooks Baseball's data.

The excellent OSFM Opening Day roster is the base, so all teams will have full minor league systems in place.

Default contracts are used as I feel that the game works best that way.

These rosters were developed with franchise mode in mind as that is my favorite mode, and I'm strictly an offline player.

Full 40 man rosters are set, as of opening day. Injured/suspended players are in single A and will remain on 40 man roster.

Notes
In franchise, I suggest making the following changes to sliders when simming games:
-starter stamina: 5
-reliever stamina: 0

I suggest using the following trade frequency settings:
April & May: 1
June-July 15th: 3
July 15th-July 31st: Max
Rest of Season: 5
Offseason & Spring Training: 6

However, one thing I noticed right away is that--regardless of trade frequency slider setting--teams will trade a lot early in the season. I use 30-team control, so what I did, and what I would suggest others do, is set CPU teams trading to "manual" for April and May.

For drafted players, I would suggest making edits during the offseason as The Show's draft logic/player generation is still a bit off (based on what I've seen in the CPU draft thread).

I will be doing the following:
-If RP/CP is selected in rounds 1-3, I will convert them to SPs.
-For the top 10 picks, if the player is 21 or older, OVR = potential - 20
-For the top 10 picks, if the player is under 21, OVR = potential - 30

For the first 2 rounds, I will try to make sure players project to fit into the following archetypes:
-Power hitter
-Contact hitter
-Balanced/All-Around hitter
-5 tool player (top picks)
-Strikeout pitcher
-Control pitcher
-Groundball pitcher
-Balanced pitcher

Rating Process & Methodology

Spoiler

Hitting and Fielding
-Contact ratings are based on AVG

-Power ratings are based on ISO and HR%

-Vision ratings are based on K%

-Discipline ratings are based on BB%

-Durability ratings are based on the league average games played per MLB season (102 games) for all position players, and then adjusted for catchers.

-Minimum durability for rookies is 80.

-Minimum durability for all other position players is 70.

-Statcast data was used for speed and arm strength ratings, or 20-80 scouting reports if none were available (often the case for rookies)


-Fielding ratings (arm accuracy, reaction and fielding ability) are position specific; catchers, infielders and outfielders are all rated differently.

-RDRS (Baseball Info Solutions Defensive Runs Saved Above Average) is factored into the calculations, which makes position specific adjustments. Statcast's OAA (Outs Above Average) is used for outfielders.

Pitchers
-Per 9 ratings are based on the per 9 statistics.

-Stamina is based on innings/appearance

-Pitch repertoires are up to date as of 2017 season, except for a few outliers e.g. Ohtani.

-Pitch ratings are based on the last 3 years of pitch data available

-Pitch control is based on strike percentage, with an adjustment for pitches that were thrown out of the strike zone and missed i.e. pitchers will benefit from those strikes

-Movement is based on whiff%

-If a pitcher’s primary pitch is a sinker, it remains a sinker

-If a pitcher uses a sinker but it is not his primary pitch, it is listed as a two-seamer. This helps sinkerballers stand out.

-Brooks Baseball's pitch descriptions were used to influence what pitches were used.

Im intrigued!

Are you gonna share your ratings calculator on here?

[bravesfan1984]

Very excited about this!

I may share it at some point. It's not user friendly enough at the moment, but I've started to make some improvements to that aspect.

I'd also be happy to discuss how I developed the ratings, and share the attributes of the teams I've already done, if there is interest.

I'd love to see some ratings.

Here are the ratings completed to date:

I have to go back and add pitch edits for a few teams (CWS, KC, MIN), but most are done.

All AL teams are done. I'm working through the NL: ATL, MIA, WSH, FLA and LAD are done.

A quick breadkdown on the ratings and the proces:

Hitting and Fielding
-Contact ratings are based on AVG

-Power ratings are based on ISO and HR%

-Vision ratings are based on K%

-Discipline ratings are based on BB%

-Clutch ratings are based on FanGraphs clutch rating system

-Durability ratings are based on the league average games played per MLB season (102 games) for all position players, and then adjusted for catchers.

-Minimum durability for rookies is 80.

-Minimum durability for all other position players is 70.

-FanGraphs fan scouting reports was used for speed and arm strength ratings, or 20-80 scouting reports if none were available (often the case for rookies)

-Fielding ratings (arm accuracy, reaction and fielding ability) are position specific; catchers, infielders and outfielders are all rated differently.

-RDRS (Baseball Info Solutions Defensive Runs Saved Above Average) is factored into the calculations, which makes position specific adjustments.

Pitchers
-Per 9 ratings are based on the per 9 statistics.

-Stamina is based on innings/appearance

-Clutch is based on FanGraphs clutch ratings

-Pitch repertoires are up to date as of last season.

-Pitch ratings are based on the last 3 years of pitch data available

-Pitch control is based on strike percentage, with an adjustment for pitches that were thrown out of the strike zone and missed i.e. pitchers will benefit from those strikes

-Movement is based on whiff%

-If a pitcher’s primary pitch is a sinker, it remains a sinker

-If a pitcher uses a sinker but it is not his primary pitch, it is listed as a two-seamer. This helps sinkerballers stand out.

Just pre-ordered the game

Made some headway into finishing up the pitch edits that were missing from the completed teams
