Why are there no double-headers anymore?

Double-headers in Major League Baseball have become less common due to several factors, including the increased focus on player health and workload management. Teams often prefer to spread games out to avoid overexerting pitchers and position players. Additionally, logistical challenges and fan preferences for single, more engaging game experiences have contributed to the decline of double-headers in the modern era. While occasional double-headers still occur, especially as make-up games, they are not part of the standard scheduling like they used to be.
