Biggest plays in San Francisco Giants history
Major League Baseball history is built on moments — swings, pitches, and split-second plays that reshaped seasons and, in some cases, entire franchises. From walk-off home runs in winner-take-all games to clutch hits under October pressure, the biggest plays often came when the stakes were highest. Stacker identified the most impactful plays in San Francisco Giants history using data from Stathead. Plays were ranked by their Championship Win Probability Added (cWPA), a metric that measures how much a single play changed a team’s odds of winning the World Series.
