This chart tracks the player's wOBA (weighted On-Base Average — a single number that summarises overall offensive value) game by game across the season. Each dot is one game's wOBA, coloured on the same scale as the calendar below (see the legend); the gold line is a 5-game rolling average that smooths out single-game swings so you can see hot and cold streaks and the overall direction of the player's production. Higher is better.

This chart tracks the player's FIP (Fielding Independent Pitching — an ERA-scaled measure of the outcomes a pitcher most controls: home runs, walks and strikeouts) game by game. Each dot is one game's FIP, coloured by quality (see the legend); the gold line is a 5-game rolling average that smooths single-game swings so you can see the direction of the player's pitching. Lower is better.
