COLUMBIA, Mo. – University of Missouri baseball announced the signing of 11 high school student-athletes to its 2027 recruiting class on National Signing Day on Wednesday.
Head coach Kerrick Jackson and his staff secured NLI’s from five Missouri standouts and six additional signees hailing from Florida, Illinois, Kansas, Mississippi and South Korea. The class is comprised of five pitchers, one catcher, one infielder, two outfielders, one utility player and one two-way player.
All five Missouri signees rank among Perfect Game’s top 25 prospects in the state’s 2027 class, including three top 10 signees. The incoming Tigers bring a combination of accomplished pitching, athleticism, defensive versatility and offensive production heading into Jackson’s fourth season.
“We’ve made recruiting the state of Missouri a priority, and we’re excited about the young men who have chosen to stay home and help us continue to build this program,” Jackson said. “There is quality pitching in this state, and keeping those arms home is an important part of building a staff that can compete in the SEC. We’re equally excited about the position players in this class, as they are an athletic and versatile group, with high baseball IQ and a competitive mentality that is off the charts. Our staff has done a great job developing relationships with these players and their families. Across this entire class, we’re adding talented players who love to compete, want to develop and believe in what we’re building at Mizzou.”
