Deep Dive Into Catcher Framing Metrics in 643 Synergy
TL;DW
- Catcher framing is a crucial skill that can be measured using run values, helping to identify opportunities for saving extra runs.
- The 643 Synergy tile divides the strike zone into eight ‘shadow zones’, allowing for detailed analysis of a catcher’s performance.
- The Catcher Framing tool provides data on the percentage of pitches converted to called strikes and the impact of winning those strikes, measured in saved runs.
- The Catcher Framing tool also highlights outliers, such as pitches in the heart of the zone called balls or those well off the plate called for strikes.
Framing+
TL;DW
- Framing+ is a metric in the Catcher Framing tool that compares a player’s performance to the league average, with 100 being the average.
- The metric takes into account the importance and impact of each pitch, not just the number of pitches won, making it a more nuanced evaluation tool.
- Even if a catcher wins more pitches than the league average, their Framing+ could be below average if they’re not winning the most impactful pitches.
Analyzing Specific Catcher Performance and Development Strategies
TL;DW
- The Catcher Framing tool highlights the importance of different pitches and their impact on the game, with the highest leverage pitches being 3-2 and 2-2.
- The tool can filter data based on batter handedness, pitcher handedness, and pitch types, providing valuable insights for developing player-specific strategies.
- Comparing performance over different date ranges can help assess the impact of changes in setup or approach, providing objective measurements for player development.
Catcher Framing and Synergy Video Playlists
TL;DW
- The Synergy Video Playlists feature in the 643 Charts platform allows users to analyze, compare, and create video playlists of pitches based on specific zones and outcomes.
- Users can provide additional context to these playlists by adding notes, making it a useful tool for post-game analysis and performance improvement.
- The tool offers an objective way to quantify a catcher’s performance, and provides insights into areas of improvement, such as pitches in the top zones.
Catchers’ Defensive Runs Saved (DRS) and WAR
TL;DW
- Defensive Runs Saved (DRS) is an aggregated measure of a catcher’s overall defense, with framing being a significant component.
- The DRS value is rolled into Wins Above Replacement (WAR), which also considers offense, base running and pitching.
- Using DRS and WAR metrics, teams can evaluate and identify undervalued catchers in the transfer portal.
