From the Didn’t See That Coming Dept., we have this score from Starkville: Texas Southern 8, Mississippi State 4. Anything can happen on a given day in baseball, but still, when a winless SWAC team takes down a consensus top 10 SEC club on its home field, that’s going to send reverberations far and wide. “This is the second-biggest win in the history of the university,” TSU coach Michael Robertson said in a school release. The only thing bigger, Robertson said, would be a 2004 NCAA regional win against defending national champion Rice. Bulldogs shortstop Jordan Westburg had this take: “This is a really big wake-up call. It should hurt. It should hurt for everybody on the team … .” TSU, now 1-9, took a 7-3 lead with a four-run fourth. K.C. Hunt and David Dunlavey, State’s first two pitchers, allowed those seven runs (only four earned) on six hits, four walks, three wild pitches and a hit batsman. The Bulldogs made two critical errors. They stranded 11 runners, scoring just once after the second inning. “We’re not competing right now in a lot of different ways,” State coach Chris Lemonis said in a school release. State (5-2), which lost to Oregon State on Sunday, returns to Dudy Noble Field today to face another SWAC school, Alcorn State, which battled Ole Miss tooth-and-nail last week before losing on an Anthony Servideo walk-off bomb. … Meanwhile, in Oxford on Tuesday, Ole Miss and Southern Miss put on a show befitting a rivalry game. The nationally ranked Rebels won 4-3, getting a clutch go-ahead homer from Hayden Leatherwood in the seventh inning and some gritty relief pitching from Braden Forsyth, who struck out two batters with the go-ahead run on base in the ninth. Leatherwood hit 22 homers the previous two years at Northwest Mississippi Community College. For USM, Will McGillis, a product of Hattiesburg’s Presbyterian Christian School, went 3-for-5 with a go-ahead homer in the top of the seventh.
