Collegiate summer baseball

Collegiate summer baseball leagues are amateur baseball leagues in the United States and Canada featuring players who have attended at least one year of college and have at least one year of athletic eligibility remaining. Generally, they operate from early June to early August. In contrast to college baseball, which allow aluminum or other composite baseball bats, players in these leagues use only wooden bats, hence the common nickname of these leagues as "wood-bat leagues". Collegiate summer leagues allow college baseball players the ability to compete using professional rules and equipment, giving them experience and allowing professional scouts the opportunity to observe players under such conditions.

To find a collegiate summer team, players work with their college coaches and prospective teams' general managers. They report to summer leagues after completing their spring collegiate season with their NCAA, NAIA, NJCAA, CCCAA, and NWAC teams. Some players arrive late due to their college team's postseason play, which sometimes runs into early June. In some cases, players are drafted during the collegiate summer season. These draftees can remain with their collegiate summer team until they sign a professional contract. During the season, players are housed by volunteer host families and bussed to and from road games.

The leagues vary greatly in their attendances, quality of play, and ability to attract scouts. The Alaska Baseball League (ABL) and the Cape Cod Baseball League (CCBL) are considered the two premier collegiate summer leagues.
