Marietta's baseball team has won six national championships, an NCAA Division III record: in 1981, 1983, 1986, 2006, 2011 and 2012. The first three were under coach Don Schaly, who died on March 9, 2005; the three most recent under coach Brian Brewer. By repeating as the national champions in 2011 and 2012 the Pioneers became the first team to do that in NCAA Division III play since the Rowan University Profs won back to back championships in 1978 and 1979. Five former Pioneer baseball players—Kent Tekulve, Duane Theiss, Jim Tracy, Terry Mulholland and Matt DeSalvo—have reached the Major League level.
