What Bullpen Day means

A bullpen day is when a team skips a traditional starting pitcher entirely and instead strings together multiple relief pitchers to cover the game. It requires its own separate handicapping approach from a standard starting-pitcher matchup, since bullpen day outcomes tend to be more volatile and harder to project using a single pitcher's season-long statistics.
