Baseball America liked the 2017 Mississippi Braves. They really liked them. Five M-Braves are in the top 10 in the magazine’s ranking of the Top 20 prospects in the Southern League. A sixth made the list, which was released today. The M-Braves’ record on the field wasn’t so great, but the talent Atlanta appears to be developing is impressive. Ronald Acuna, BA’s minor league player of the year, was rated No. 1 in the SL. Look for him in the outfield at SunTrust Park next season. Young pitchers Mike Soroka (ranked No. 4), Luiz Gohara (5), Kolby Allard (10) and Max Fried (19) could be key pieces in the Atlanta rotation in the not-so-distant future. Gohara and Fried already have big league wins on their resumes. Austin Riley, the former DeSoto Central High star, was ranked No. 6 by BA’s editors, who raved about his raw power. He hit eight homers in 178 at-bats as a 20-year-old in Double-A. He’ll challenge for Atlanta’s third-base job soon enough. … Two Biloxi Shuckers made the Top 20: right-handers Corbin Burnes (No. 8) and Luis Ortiz (11). Burnes was Milwaukee’s pick as its minor league pitcher of the year after going 3-3 with a 2.10 ERA for Biloxi and 5-0, 1.05 in A-ball.
