Conference play starts this weekend for the state’s Big 3 Division I schools. Each is playing at home, and there should be an upbeat vibe for all three. Southern Miss is nationally ranked, sports a 12-4 record and just blasted Tulane 12-3 on Wednesday night in New Orleans. And there’s even more good news for Golden Eagles fans: Matt Wallner is heating up. The 2017 national freshman of the year homered against the Green Wave, just his second of the year but second in the last three games. Wallner, a .336 hitter with 19 bombs in 2017, is batting .298. USM opens Conference USA play against Texas-San Antonio in Hattiesburg. Ole Miss, which welcomes Tennessee to Oxford to launch SEC play, is on an even steeper roll. The Rebels, a top 10 team, bashed Georgia State 16-2 on Wednesday in Atlanta to move to 17-1. Who’s hot? Cole Zabowski, to pick just one. He went 3-for-4 with a home run and four RBIs vs. the Panthers and is at .310 with three homers and 13 RBIs on the season. Mississippi State stumbled on Wednesday, losing to Southeastern Louisiana 11-5 in Biloxi. Jake Mangum continued to swing a hot bat, however, going 2-for-5. He is hitting .351 with 11 runs and seven steals. The Bulldogs take a 10-7 record into their SEC series against Vanderbilt in Starkville, but note they are 4-1 at renovated Dudy Noble Field, where the home-field edge is palpable. P.S. Jackson State, 5-1 in the SWAC, takes on Alabama State (4-2) this weekend in Montgomery in a key league series. JSU is 12-4 overall after a twinbill split at Morehead (Ky.) State. In a 4-0 win that was halted by snow on Tuesday and completed Wednesday, Jesus Santana hit his fourth homer of the year. Jarvis Warner has boosted his average to .364.
