MLB Stats API

Getting Started

Python-mlb-statsapi is a Python library that provides access to the MLB Stats API, allowing developers to retrieve information related to MLB teams, players, stats, and more. Written in Python 3.10+.

All models are built with Pydantic for robust data validation and serialization. Field names follow Python's snake_case convention for a more Pythonic experience.

For detailed documentation, check out the Wiki which contains information on return objects, endpoint structure, usage examples, and more.

Installation

python3 -m pip install python-mlb-statsapi

Quick Start

>>> import mlbstatsapi
>>> mlb = mlbstatsapi.Mlb()

>>> mlb.get_people_id("Ty France")
[664034]

>>> player = mlb.get_person(664034)
>>> print(player.full_name)
Ty France

>>> stats = ['season', 'seasonAdvanced']
>>> groups = ['hitting']
>>> params = {'season': 2022}
>>> mlb.get_player_stats(664034, stats, groups, **params)
{'hitting': {'season': Stat, 'seasonAdvanced': Stat }}

>>> mlb.get_team_id("Seattle Mariners")
[136]

>>> team = mlb.get_team(136)
>>> print(team.name, team.franchise_name)
Seattle Mariners Seattle

HTTP Sessions, Timeouts, and Retries

Version 0.8.0 adds shared HTTP Sessions, explicit timeouts, optional Session injection, bounded retries, and structured transport exceptions. The Mlb client remains synchronous. Shared Sessions pool reusable connections; they do not cache MLB response bodies, and the client does not enable response caching by default.

Recommended context-manager usage

Prefer a context manager so library-owned HTTP resources are closed when the block exits, including when the block exits because of an exception:

import mlbstatsapi

with mlbstatsapi.Mlb() as mlb:
    player = mlb.get_person(664034)
    team = mlb.get_team(136)

One Mlb client uses one shared requests.Session. The v1 and v1.1 adapters share that Session, so repeated requests can reuse pooled connections. A Session manages a pool of reusable connections; it is not one permanent network connection.

Existing construction remains valid

Existing construction continues to work:

import mlbstatsapi

mlb = mlbstatsapi.Mlb()
player = mlb.get_person(664034)

Callers who do not use a context manager may call mlb.close(). Repeated close() calls are safe.

Custom timeouts

Every request uses an explicit timeout. The defaults are:

Connection timeout: 3.05 seconds
Read timeout: 30 seconds

The read timeout is the maximum wait while reading response data. It is not one absolute total duration for the complete request.

Use a scalar to apply the same value to both connect and read phases:

import mlbstatsapi

with mlbstatsapi.Mlb(timeout=10) as mlb:
    player = mlb.get_person(664034)

Or provide separate connection and read timeouts:

import mlbstatsapi

with mlbstatsapi.Mlb(
    timeout=(5.0, 60.0),
) as mlb:
    player = mlb.get_person(664034)
5.0 seconds: connection timeout
60.0 seconds: read timeout

Injecting a custom Session

Advanced callers may inject a caller-owned Session:

import requests
import mlbstatsapi

session = requests.Session()
session.headers.update({
    "User-Agent": "my-baseball-project/1.0",
})

try:
    with mlbstatsapi.Mlb(session=session) as mlb:
        player = mlb.get_person(664034)
finally:
    session.close()

Ownership rules:

Library-created Session
    The library owns and closes it
Caller-injected Session
    The caller owns and closes it

Mlb.close() does not close a caller-injected Session, and exiting with Mlb(session=session) does not close the injected Session either. The library does not replace or reconfigure adapters on an injected Session. Callers control custom retry, TLS, proxy, and adapter configuration.

Structured exception handling

import mlbstatsapi

try:
    with mlbstatsapi.Mlb() as mlb:
        player = mlb.get_person(664034)
except mlbstatsapi.MlbTimeoutError:
    print("The MLB API timed out")
except mlbstatsapi.MlbTransportError:
    print("The request could not reach the MLB API")
except mlbstatsapi.MlbHttpError as exc:
    print(
        exc.status_code,
        exc.reason,
        exc.url,
    )
except mlbstatsapi.MlbDecodeError:
    print("The MLB API returned invalid JSON")
  • MlbTimeoutError represents connection and read timeouts
  • MlbTransportError represents other request transport failures
  • MlbHttpError represents an unexpected final HTTP response
  • MlbDecodeError represents invalid JSON in a successful response

Backward-compatible exception handling

All new transport exceptions inherit from TheMlbStatsApiException, so existing broad exception handling remains compatible:

import mlbstatsapi

try:
    with mlbstatsapi.Mlb() as mlb:
        player = mlb.get_person(664034)
except mlbstatsapi.TheMlbStatsApiException:
    print("The MLB request failed")

Default retry behavior

Library-created Sessions automatically retry temporary GET failures for:

429
500
502
503
504
Initial request: 1
Maximum retries: 3
Maximum total attempts: 4
Backoff factor: 0.5
Retry-After respected: yes

Only GET requests are retried, and retries are bounded. Ordinary client errors such as 400, 401, 403, and 404 are not retried. Invalid JSON and Pydantic validation failures are not retried. Retries improve resilience for transient failures, but they do not guarantee success.

Existing 404 compatibility

Version 0.8.0 preserves existing endpoint-specific not-found behavior. Depending on the endpoint, a 404 may still produce:

None
[]
{}

Not every 404 raises MlbHttpError.

See the HTTP transport documentation for the complete retry policy, Session ownership rules, cleanup behavior, and exception hierarchy.

Working with Pydantic Models

All returned objects are Pydantic models, giving you access to powerful serialization and validation features.

Convert to Dictionary

>>> player = mlb.get_person(664034)
>>> player.model_dump()
{'id': 664034, 'full_name': 'Ty France', 'link': '/api/v1/people/664034', ...}

# Exclude None values
>>> player.model_dump(exclude_none=True)
{'id': 664034, 'full_name': 'Ty France', 'link': '/api/v1/people/664034', ...}

# Include only specific fields
>>> player.model_dump(include={'id', 'full_name', 'primary_position'})
{'id': 664034, 'full_name': 'Ty France', 'primary_position': Position(...)}

Convert to JSON

>>> player = mlb.get_person(664034)
>>> player.model_dump_json()
'{"id": 664034, "full_name": "Ty France", "link": "/api/v1/people/664034", ...}'

# Pretty print with indentation
>>> print(player.model_dump_json(indent=2))
{
  "id": 664034,
  "full_name": "Ty France",
  "link": "/api/v1/people/664034",
  ...
}

Access Fields with Snake Case Names

>>> player = mlb.get_person(664034)
>>> player.full_name          # Not fullName
'Ty France'
>>> player.primary_position   # Not primaryPosition
Position(code='3', name='First Base', ...)
>>> player.bat_side           # Not batSide  
CodeDesc(code='R', description='Right')

Contributing

Contributions are welcome! Whether it's bug fixes, new features, or documentation improvements, we appreciate your help.

Getting Started

  1. Fork the repository
  2. Clone your fork: git clone https://github.com/YOUR_USERNAME/python-mlb-statsapi.git
  3. Install dependencies: poetry install
  4. Create a branch: git checkout -b feat/your-feature

Development

Offline tests are deterministic and should run before every pull request:

poetry run pytest \
  tests/ \
  --ignore=tests/external_tests

External tests contact the live MLB API. They require internet access and are separate from normal offline CI:

poetry run pytest \
  tests/external_tests/

These live tests may fail because the MLB service is unavailable or because MLB changes undocumented payloads.

Full local validation:

poetry run pytest tests/
poetry build

Offline CI is the normal pull-request gate. External tests are available manually, on a weekly schedule, and before releases.

Examples

Let's show some examples of getting stat objects from the API. What is baseball without stats, right?

Player Stats

Get the Id(s) of the players you want stats for and set stat types and groups.

>>> mlb = mlbstatsapi.Mlb()
>>> player_id = mlb.get_people_id("Ty France")[0]
>>> stats = ['season', 'career']
>>> groups = ['hitting', 'pitching']
>>> params = {'season': 2022}

Use player id with stat types and groups to return a stats dictionary

>>> stat_dict = mlb.get_player_stats(player_id, stats=stats, groups=groups, **params)
>>> season_hitting_stat = stat_dict['hitting']['season']
>>> career_pitching_stat = stat_dict['pitching']['career']

Print season hitting stats using Pydantic's model_dump()

>>> for split in season_hitting_stat.splits:
...     print(split.stat.model_dump(exclude_none=True))
{'games_played': 140, 'groundouts': 163, 'airouts': 148, 'runs': 65, 'doubles': 27, ...}

Or access individual fields directly

>>> for split in season_hitting_stat.splits:
...     print(f"Games: {split.stat.games_played}")
...     print(f"Home Runs: {split.stat.home_runs}")
...     print(f"Batting Avg: {split.stat.avg}")
Games: 140
Home Runs: 20
Batting Avg: .274

Team Stats

Get the Team Id(s)

>>> mlb = mlbstatsapi.Mlb()
>>> team_id = mlb.get_team_id('Seattle Mariners')[0]

Set the stat types and groups

>>> stats = ['season', 'seasonAdvanced']
>>> groups = ['hitting']
>>> params = {'season': 2022}

Use team id and the stat types and groups to return season hitting stats

>>> stats = mlb.get_team_stats(team_id, stats=stats, groups=groups, **params)
>>> season_hitting = stats['hitting']['season']
>>> advanced_hitting = stats['hitting']['seasonAdvanced']

Print stats as JSON

>>> for split in season_hitting.splits:
...     print(split.stat.model_dump_json(indent=2, exclude_none=True))
{
  "games_played": 162,
  "groundouts": 1273,
  "runs": 690,
  "doubles": 229,
  ...
}

Expected Stats

>>> player_id = mlb.get_people_id('Ty France')[0]
>>> stats = ['expectedStatistics']
>>> group = ['hitting']
>>> params = {'season': 2022}

>>> stats = mlb.get_player_stats(player_id, stats=stats, groups=group, **params)
>>> expected = stats['hitting']['expectedStatistics']
>>> for split in expected.splits:
...     print(f"Expected AVG: {split.stat.avg}")
...     print(f"Expected SLG: {split.stat.slg}")
Expected AVG: .259
Expected SLG: .394

vsPlayer Stats

Get pitcher and batter player Ids

>>> ty_france_id = mlb.get_people_id('Ty France')[0]

Set stat type, stat groups, and params

>>> stats = ['vsPlayer']
>>> group = ['hitting']
>>> params = {'opposingPlayerId': shohei_ohtani_id, 'season': 2022}

Get stats

>>> stats = mlb.get_player_stats(ty_france_id, stats=stats, groups=group, **params)
>>> vs_player = stats['hitting']['vsPlayer']
>>> for split in vs_player.splits:
...     print(f"Games: {split.stat.games_played}, Hits: {split.stat.hits}")
Games: 2, Hits: 2

Hot/Cold Zones

>>> ty_france_id = mlb.get_people_id('Ty France')[0]
>>> stats = ['hotColdZones']
>>> hitting_group = ['hitting']
>>> params = {'season': 2022}

>>> hotcoldzones = mlb.get_player_stats(ty_france_id, stats=stats, groups=hitting_group, **params)
>>> zones = hotcoldzones['stats']['hotColdZones']

>>> for split in zones.splits:
...     print(f"Stat: {split.stat.name}")
...     for zone in split.stat.zones:
...         print(f"  Zone {zone.zone}: {zone.value}")
