A large number of players in Major League Baseball don't make it to the professional ranks by way of college, instead signing with a team right out of high school or joining as an international free agent.

But many do make their marks going up against NCAA opponents, using their college years to grow as a person and player and turn the heads of scouts who come to observe.

With the 2016 MLB playoffs beginning Tuesday night with the American League Wild Card Game, here is a quick look at the schools with the most alumni on the 10 playoff rosters. Overall, 181 players on the 40-man rosters of the 10 playoff teams were once NCAA student-athletes.
