TheSt. Mary's Rattlers are the athletic teams that representSt. Mary's University, Texas, located inSan Antonio, Texas, United States inNCAA Division II intercollegiate sporting competitions. The Rattlers compete as members of theLone Star Conference for all 11 varsity sports. St. Mary's was a member of theHeartland Conference from 1999 to 2019.^[2]

Before St. Mary's was recognized as a senior college in 1925, there was no formal conference competition, so the rivalry between the downtown and Woodlawn campuses was fierce. St. Mary's was an all-male school for more than a century. Women's intercollegiate athletics, begun in 1968, have enjoyed many triumphs.

Interscholastic athletics competition began with baseball in 1902.^[3] The colorful history of St. Mary's athletics includes a stellar 1910 baseball team, which lost only toTy Cobb'sDetroit Tigers in an exhibition game, Records show the 1902 baseball team went 6–0, and the 1910 squad also went undefeated except for the aforementioned game against the Tigers. With the onset of the Depression, intercollegiate baseball disappeared only to be resurrected in 1947 by then-athletics director Brother Bill Siemer, S.M. Over the years, St. Mary's baseball has won local, regional and national fame. Accomplishments include 24 conference championships, four NAIA College World Series appearances and, most recently, the 2001 NCAA Division II conference, regional and national championships.

St. Mary's first individual national championship came in 2006, when Jamie Amoretti won the NCAA Division II Men's Golf title. The Men's Golf team would be named theGolf Coaches Association of America 2008–2009 Academic National Champions, a title which St. Mary's treats as a fifth team national championship.^[4]

In 1916, the football team was coached by future U.S. presidentDwight Eisenhower.^[3] In 1939, both Collier's and Life magazines feature full-page spreads on the St. Mary's football team and their cross country trips in a ragged bus, the "Blue Goose". The team was disbanded due to World War II.^[3] Following the end of intercollegiate football at the start of World War II, there have been at least three attempts to revive full-contact sports on campus: a club football team in the early 1970s, a club rugby team in the early 1990s, and a Texas Rugby Union Collegiate Division III team formed in Fall 2010.^[3][5]

The softball team has led the way, winning several conference titles, playing in the NAIA and NCAA Division II national tournaments, and winning the 1986 NAIA National Championship and the 2002 Division II National Championship.^[3]

Basketball head coach and athletics director Herman A “Buddy” Meyer has also been inducted into the Heartland Conference Hall of Fame.^[6]

St. Mary's has won four team national championships in men's basketball (1989), baseball (2001), softball (1986 and 2002), and one individual national title in men's golf (2006).

The Rattler mascot has its own stories of how it came to be. Legend holds that the football practice field had to be cleared of diamondback rattlesnakes on a regular basis, thus leading to the designation. The truth is that Brother Kinsky thought “Rattlers” would be fitting because there was already on campus Rattler Club whose members had recently begun The Rattler newspaper. There was debate as to whether the name was being run into the ground, but the students quickly said they wanted the Rattler nickname.^[8]

Alton Seekatz (B.S.C. ’32), a member of the Rattler Club, described the organization as a spirit and social organization. “It was called the Rattler Club when I got here in 1926, and I’m not sure how it got its nickname,” he said, although his stories of the club members' antics and efforts to raise school spirit would certainly “rattle” some and “shake” up others.
