Red-hot Alex Jackson banged out a couple more hits, including a home run, in the Mississippi Braves’ loss to Pensacola at Trustmark Park on Wednesday night. He is 10-for-23 with two bombs and seven RBIs in his last five games. If you follow the MLB draft – and who doesn’t, right? – you may remember the name Alex Jackson. In 2014, he was a high school phenom in San Diego, a big masher considered to be one of the best hitters available, a possible No. 1 overall pick. Seattle took him with the sixth selection, and for two years he sat atop their prospect chart. For whatever reason, the Mariners soured on Jackson. After the 2016 season, when he hit .243 with 11 homers and 103 strikeouts in low-A ball, the M’s traded Jackson to Atlanta in a minor league deal. Seattle had converted the 6-foot-2, 215-pound Jackson from catcher to the outfield; the Braves moved him back behind the plate, a switch Jackson reportedly was eager to make. He started 2017 at high-A Florida, hit .270 with 14 homers and 45 RBIs in 66 games and began to revive some of the old hype. He was promoted to Double-A on July 30. After a slow start, Jackson’s recent surge has raised his average to .239 in 12 games. … Also on fire for the M-Braves is Austin Riley, the ex-DeSoto Central High star who was a first-round supplemental pick in 2015. The 20-year-old third baseman, who also started 2017 at Florida, is hitting .364 with two homers and 10 RBIs over his last 10 games and is at .276 with four homers in 29 Double-A games. … And up at Triple-A Gwinnett, Ronald Acuna, the Braves’ No. 1 prospect, is batting .341 with seven homers and is banging on the big-league door. The 19-year-old outfielder, who also started this season in A-ball, blew through Mississippi, hitting .326 with nine bombs in 57 games. P.S. Madison Central product Spencer Turnbull, pitching in the Detroit system, got roughed up in his Double-A debut on Wednesday night. He allowed six hits, five walks and six earned runs in 4 1/3 innings for Erie in the Eastern League. The 2014 second-round pick out of Alabama was 7-3 with a 3.05 ERA in high-A ball this season.
