Game 1 of a four-game International League series in Lawrenceville, Ga., on Monday featured the Triple-A debut of former DeSoto Central High star Austin Riley, who went 1-for-5 for Atlanta affiliate Gwinnett. Game 2 could see the Class AAA debut of ex-George County High and Southern Miss standout Mason Robbins, now with Charlotte. Robbins, 25 and in his fifth pro season, was promoted by the Chicago White Sox on Monday. The left-handed hitting outfielder started this season on the disabled list but after being activated hit .350 with a homer and three RBIs in five games for Double-A Birmingham. He batted .265 with three homers in 125 games for the Barons in 2017. “I want to get more out of my swing than what I had last year,” Robbins told the Biloxi Sun-Herald in February, meaning he needs to show more power. In 2016 in high-A ball, he hit five homers with 33 doubles and seven triples while batting .314 and making the Carolina League’s postseason All-Star team. If Robbins starts tonight, he’ll face Gwinnett’s Kolby Allard, the former Mississippi Braves lefty who rates as one of Atlanta’s top prospects.
