The Magnolia State’s NCAA Division I schools should get some good barometer readings this weekend. Mississippi State, 16-1 and ranked in everybody’s top 10, gets its first true road test of the season when it opens SEC play at nationally ranked Florida (14-5). Nationally ranked Ole Miss (12-5) starts league play with a home series against Alabama, 16-2 but unranked. Southern Miss, wobbling a bit at 8-6, begins defense of its C-USA regular season title at Louisiana Tech (11-5), which features a bunch of Mississippi connections, including coach Lane Burroughs, a former USM assistant. And at Magnolia Field in Itta Bena, Jackson State and Mississippi Valley State, both still feeling their way, will lock up in a big SWAC series. JSU is 5-13 (1-2 SWAC) against a schedule that has included Boston College, Mississippi State, UNO and Miami (Fla.). Weather issues have limited Valley to six games; the Delta Devils are 1-5 (0-1 SWAC), including an 8-1 loss at Memphis on Tuesday, and have not played a home game. Equon Smith leads JSU hitters with a .348 average and has scored 15 runs. Raul Hernandez is at .309 with two homers and 16 RBIs. Wesley Reyes (.208) and Dezmond Chumley (.190), preseason All-SWAC picks, have yet to click. Morgan Lomax is hitting .409 for Valley, and Billy Leflore checks in at .381. Neither club has pitched particularly well, and that’ll probably be the key to the series. JSU has a 5.89 ERA, though Kevin Perez (2-1, 3.38) and Garth Cahill (2.18 in nine appearances) have been solid. Valley is at 9.56, having only once held an opponent to fewer than eight runs. Aaron Barkley has the lone win and a 1.50 ERA in six innings of work.
