Hattiesburg native and onetime big leaguer Robert Carson is still out there chucking it in the hinterlands of pro baseball. Carson is a main bullpen piece for Southern Maryland, which won the first-half title in the Freedom Division of the independent Atlantic League. The Atlantic League, which is filled with a lot of veteran talent, is in the last week of its regular season with the playoffs looming. Carson, 28, a large left-hander, has a 4.00 ERA and a 3-4 record in 55 games for the Blue Crabs. He is in his 11th pro season, with 447 appearances on his ledger, including 31 for the New York Mets in 2012-13. Also in the league is former Ole Miss pitcher Hawtin Buchanan, who has put up a 3.26 ERA in 37 games as a reliever for York. The Revolution is close to clinching the second-half race in the Freedom Division. The 6-foot-8 Buchanan, originally drafted by Seattle in 2014, was released by Cincinnati in the spring. Alcorn State product Angel Rosa is the shortstop for Bridgeport, hitting .219 with two homers and 16 RBIs for a team that has the league’s best overall record but likely will miss the playoffs. Rosa, who played in the Southern League for Mobile this year, was released in mid-summer by the Los Angeles Angels. Jackson native Stan Cliburn, a veteran Atlantic League manager, is the skipper in New Britain, but his Bees are not a postseason contender in 2017.
