...that SEC Baseball did not exist prior to Polk is just absurd. In Mississippi alone, UM's Tom Swayze and MSU's Paul Gregory had a nice rivalry built up in the 1960's into the early 70's. For the nine years from 1964 to 1972, UM and MSU won 7 of the SEC titles (MSU 4, UM 3).
In 1970, the Dogs went to old Swayze Field (then called University Park) needing only one win to clinch the West. Ole Miss swept the Friday DH on May 8 in front of 4,220 (1st game) and 4,300 (nightcap), setting up a winner-take-all showdown on Saturday. The great LHP Brantley Jones threw a 3-0 shutout for MSU and reportedly shot the then-state record crowd of 5,000 (many UM students during exams) the bird after the final out. I have pictures of the games and they had to rope off portions of the 1st-base and 3rd-base lines for standing-room only. Since only one SEC team went to a regional back then, Ole Miss stayed home at 25-8 (11-6). State won the SEC playoff and lost in the regionals to finish 32-8 (11-4).
The next year was Swayze's last, and UM had a rare losing season. In the series in Starkville, MSU unveiled lights for the first-ever night games at Dudy Noble Field, which had only been around about 5 years. MSU swept the Rebels in 3 close games en route to a repeat SEC championship and State's first-ever trip to Omaha. The previous year's state attendance record was smashed as MSU drew up to 9,000 for one of the games. Note that Jake Gibbs took over for the Rebs the next year and promptly led UM to a SEC Championship and a the Rebs' 4th trip to Omaha in his inaugural season of 1972. Hard to believe now, but when UM took that 4th trip in 1972, no other of the 9 SEC schools had been more than once. And at least two of Ole Miss's best teams (SEC Champs in 1959 and 1960) were prohibited from competing in the NCAA's due to the College Board's stance on integration (this was the ban MSU broke in basketball in 1963).
This doesn't count many great players and teams at Alabama and Auburn and Florida and elsewhere. This myth that SEC Baseball began with Polk is a disservice to many, and has been perpetuated by Rick Cleveland and others. One of the reasons Polk was even interested in MSU in the mid-70's is that Starkville hosted some NCAA regionals in the early 70's without the Dogs even in the tourney. Polk's Georgia Southern team qualified for Omaha through Starkville, and he noted the potential then.
