2021 CSBN Top 10 Collegiate Summer Baseball Leagues
Collegiate Summer Baseball Network is the largest directory of summer leagues and teams anywhere. For the third year (not published in 2020 due to Covid-19 related cancellations), CSBN has compiled a database of nearly 10,000 players on the rosters of over 300 teams in 33 summer leagues. We’ve scored each player based on the competition level of his college program.
Points were given for each NCAA level as well as for Junior Colleges, NAIA, NCCAA, CCCAA and NWAC. Extra credit was given for P5 and G5 conference teams as well as for top 25 ranked programs. Upper classmen were given higher scores than underclassmen.
The average roster scores of league cohorts determines league ranking.
