 # Dataset Card for Dataset Name
 
 <!-- Provide a quick summary of the dataset. -->
 
-This dataset card aims to be a base template for new datasets. It has been generated using [this raw template](https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/templates/datasetcard_template.md?plain=1).
+2.6 million clips of balls and called strikes from MLB games from the 2016 season through the 2023 season.
 
 ## Dataset Details
 
 ### Dataset Description
 
 <!-- Provide a longer summary of what this dataset is. -->
-
-
+The dataset consists of all listed balls and called strikes from Baseball Savant's [Statcast Search](https://baseballsavant.mlb.com/statcast_search) from 2016, when their video archives began, through the 2023 season.
+This dataset includes the date, type (eg. FF, fourseam fastball), mpt, spin rate, pitcher, batter, zone (1-14, corresponding to strike zone locations), count, inning, pitch result, and link to the video of the pitch.

+The original dataset, [Picklebot-50K](https://huggingface.co/datasets/hbfreed/Picklebot-50K), was collected to call balls and strikes using a neural network, and is only labeled with ball or strike.
+With the additional metadata, one can imagine much more interesting classification and granular tasks like classifying pitch types.
 
 ## Dataset Structure
 
 <!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->
+The dataset is three JSON files, split into train (80%), val (10%), and test (10%) files. They are structured as follows:
+{

+    "pitch": "CU",
+    "mph": "73.6",
+    "spin_rate": "1997",
+    "pitcher": "Garza, Matt(R)",
+    "batter": "Jaso, John(L)",
+    "zone": "8",
+    "count": "0-1",
+    "inning": "Bot 5",
+    "pitch_result": "Called Strike",
+    "video_link": "https://baseballsavant.mlb.com/sporty-videos?playId=e790b6cf-7ac4-45b8-8cd3-9cef03d759cb"

+First, as with Picklebot-50K, only balls and called strikes were connected. Additionally, this dataset is quite unbalanced: about two-thirds of the pitches are balls, and almost half of them are fourseam fastballs (see the plots below).
+One should take care dealing with these imbalances.
