So many proverbial big games to track this weekend. The regular season rolls toward a climax for the NCAA Division I programs. Mississippi State is at South Carolina and Ole Miss at Texas A&M in the SEC, Southern Miss hosts Middle Tennessee State in C-USA and Jackson State (shooting for an unbeaten SWAC season) hosts Mississippi Valley State (shooting for its first win). (Note: Valley, 0-17, hasn’t played since April 18, when the Delta Devils blew a three-run lead in the bottom of the ninth and lost 8-7 to Alabama A&M.) The small colleges are in postseason play. Today, in the NAIA SSAC Tournament at Mobile, Ala., fifth-seeded William Carey (30-10) plays 4-seed Mobile and 7-seed Blue Mountain (14-18) gets 2-seed Faulkner in the first round. In NCAA Division III, Belhaven (20-16) meets East Texas Baptist today in the first round of the ASC Tournament at Marshall, Texas. Division II Delta State (24-15) opens play Friday in the GSC Tournament in Oxford, Ala. The fifth-seeded Statesmen, who have won 15 GSC tourney titles, meet 4-seed Valdosta State in the opening round. And the state junior college playoffs begin Friday with the best-of-3 series that will send four teams to the NJCAA Region 23 Tournament next week. Third-ranked Pearl River Community College has clinched its regional berth and will host the tourney. The high school playoffs are under way, with the series opener of several MHSAA Class 6A heavyweight bouts set for tonight: MaxPreps No. 2-ranked Madison Central is at South Panola; No. 9 Tupelo hosts No. 12 Oxford; No. 4 Germantown visits No. 14 DeSoto Central; and No. 7 Lewisburg visits Starkville. In MAIS 5A, MaxPreps No. 1 Jackson Prep, up 1-0 in the series, plays Jackson Academy on Friday.
