Each of the state’s Big 3 is ranked in multiple preseason polls, testament to the talent they return from championship teams in 2018. But there will be opportunities for newcomers to step up. With the start of the 2019 NCAA Division I season upon us, here are some newbies of note at Mississippi State, Ole Miss and Southern Miss: At State, freshman J.T. Ginn should need no introduction. Already pegged as a second-team All-America by Baseball America, the ex-Brandon High star — and first-round pick by the Los Angeles Dodgers last June — is expected to pitch and hit for the Bulldogs. Slightly less heralded among the State newcomers is Gunner Halter, a junior college transfer who could also have a major impact. The son of former major leaguer Shane Halter, Gunner figures to start at second base. He goes 6 feet 3, 180 pounds and slugged 29 homers in two years at Seminole (Okla.) State. He was drafted in 2017 and 2018. “He can do a lot of special things,” State coach Chris Lemonis said of Halter at media day. … The newcomer generating most of the buzz at Ole Miss is Gunnar Hoglund, the two-way star from Florida who was the 36th overall pick by Pittsburgh in last summer’s draft. But another freshman to watch is outfielder Josh Hall. Considering how stacked the Rebels are in the outfield, Hall may find playing time hard to come by, but he has a certain set of skills that could prove valuable. The Alabama native set a national prep record with 224 career steals, including 82 bags as a senior. In addition to his speed, he is also reputed to be a great bunter. The 5-foot-9, 185-pound Hall was a first-team prep All-America pick and his state’s Class 6A player of the year. … At USM, true freshman Danny Lynch is expected to start at third base, filling the job vacated by C-USA hitter of the year and pro draftee Luke Reynolds. Florida native Lynch is the younger brother of ex-USM star Tim Lynch, who played three years in the New York Yankees’ system. Danny Lynch, listed at 6 feet 2, 225 pounds, is expected to provide some left-handed power for the Golden Eagles. “We really just have this great lineup. It’s easy, I just have to go out and play my role,” Lynch told the school newspaper, the Student Printz.
