Key Factors That Influence a No Hitter in the World Series

In addition, postseason rosters often feature deeper bullpen depth, which allows managers to deploy fresh arms in high-leverage spots.
Advanced metrics such as expected batting average on balls in play and hard-hit rate help explain why some no-hit bids survive while others break up in extra innings.
