Friday is the main event in college baseball’s regular season. Typically, Friday means the conference series opener. It means the aces are out. It’s a night when the lights are brightest and the tension most palbable. It’s when momentum is seized for the best-of-3 series. Or is it? Mississippi State and Ole Miss open their annual SEC battle tonight in Oxford with their best starters on the mound. State left-hander Ethan Small has been dominant: 6-1, 1.85 ERA, 122 strikeouts and 18 walks in 73 innings. UM’s Will Ethridge doesn’t have that kind of stuff but has been solid: 5-4, 2.80. Meanwhile, Southern Miss, trying to keep a grip on first place in C-USA, visits Rice and will throw its most reliable starter, Walker Powell (5-2, 2-79). State (15-9 SEC) has won six of its eight conference series. Only once have the Bulldogs lost the opening game and won the series. Ole Miss (also 15-9 in league) has won five SEC series, three of those after winning Game 1. Like State, UM only once has lost a league series after winning the opener. (Notably, the Rebels lost the opening game at LSU last weekend but came back to win the series in a wild rubber game.) USM (18-6 C-USA) has won five of eight series, winning none after losing the opener. What’s it all mean? Friday is a pretty big deal.
