It’s just a footnote — but one of significant local interest — on today’s Atlanta-Milwaukee National League Division Series opener. The clubs, meeting for the first time in the postseason, have a rivalry on the Double-A level, where the Mississippi Braves and Biloxi Shuckers reside. The expected pitching matchups for the first three games feature a former M-Brave vs. a former Shucker: Charlie Morton-Corbin Burnes, Max Fried-Brandon Woodruff and Ian Anderson-Freddy Peralta. No weak links there. Both bullpens are also populated with several pitchers who toiled in the Magnolia State en route to the big leagues, most notably Brewers closer Josh Hader, a nasty left-hander. The Brewers are without setup man (and Shuckers alum) Devin Williams, who broke his hand punching a wall last month after the Brewers clinched the NL Central. Atlanta’s dynamic infield is homegrown: Freddie Freeman, Ozzie Albies, Dansby Swanson and Austin Riley all passed through Pearl. By contrast, Milwaukee’s lineup was built with players from other organizations. … There is speculation that catcher Shea Langeliers, a 2021 M-Braves star and Atlanta’s minor league player of the year, could make the NLDS roster. He made the trip to Milwaukee. … The Braves and Brewers split six regular season games in 2021. One stands out. On July 31, the Braves beat Woodruff — with the aid of a bad call. It was 1-1 in the sixth inning at Truist Park when Swanson took an apparent third strike for the second out. Swanson dropped his head and started to walk to the dugout. But the pitch was called a ball. So, of course, Swanson hit the next pitch out of the park for a 3-1 lead, ending Woodruff’s night. The big right-hander glared at home plate umpire C.B. Bucknor as he left the field. … Looking ahead to Game 2, when Mississippi prep products Riley and Woodruff will face off: DeSoto Central alum Riley is 1-for-8 with a walk and two strikeouts against Wheeler High alum Woodruff. … The Braves won a World Series in 1957 when the franchise was located in Milwaukee. The Brewers have been to the Fall Classic once, as an American League team in 1982, falling to St. Louis.
