Build an MLB Standings Tracker
Create a real-time division standings board using the Baseball API standings endpoint.
Project Overview
In this tutorial, you'll build a standings tracker that displays MLB division standings with wins, losses, winning percentage, and games behind. We'll fetch data from the Baseball API and create a clean, responsive UI.
Prerequisites
- An API4Sports API key with Baseball access
- Basic knowledge of JavaScript/TypeScript
- Node.js or a frontend framework (Vue, React, etc.)
Step 1: Fetch League Data
First, get the league ID for MLB (or any league you want to track).
Step 2: Fetch Standings
Use the league ID to fetch current standings, grouped by division.
Step 3: Data Structure
The standings endpoint returns teams grouped by division with these fields:
- position - Current rank in division
- team_name - Full team name
- team_logo - Team logo URL
- wins - Total wins
- losses - Total losses
- pct - Winning percentage (0.623 = 62.3%)
- gb - Games behind division leader ('-' for first place)
Step 4: Create the UI Component
Here's a Vue 3 component example for displaying standings:
Step 5: Add Caching
Standings don't change frequently. Cache results for 15-30 minutes to reduce API calls.
Step 6: Add Division Filters
Let users filter by American League or National League:
- AL divisions: AL East, AL Central, AL West
- NL divisions: NL East, NL Central, NL West
- Show all 6 divisions or filter by conference
Enhancement Ideas
- Add wild card standings calculation
- Show team streaks (W5, L3) from games endpoint
- Display last 10 games record
- Add playoff clinch/elimination magic numbers
- Compare standings across multiple seasons
API Rate Limits
Monitor your daily request limit. For standings, refreshing every 15-30 minutes is sufficient since standings only change after games complete.
