After a sluggish start at the Triple-A level, Mason Robbins has kicked into gear the last couple of weeks. The former George County High and Southern Miss star is batting .385 over his last 10 games for Charlotte, the Chicago White Sox’s top minor league affiliate. Robbins was hitting just .227 through 18 games for the Knights when he hit his first homer on May 29. Something may have clicked. In his next game, the lefty-hitting corner outfielder went 3-for-4, and he’s been rolling ever since, lifting his average to .284. He has two homers, 17 RBIs, 14 runs, four doubles and three triples. Robbins, 25 and in his fifth pro season, has hit at every level, sporting a .285 career average. He has acknowledged that he needs to hit for more power. For some, that’s the last tool to develop, and it might be the key for Robbins to reach the big leagues. P.S. Robbins’ brother Walker, a fifth-round pick out of George County by St. Louis in 2016, is on the roster of the rookie-level Johnson City club, which opens next week. Walker Robbins, also a lefty-hitting outfielder, has hit .179 over his first two seasons. Expect him to pick it up in 2018. … A third Robbins brother, Logan, went 7-1 with a 4.66 ERA this season as a redshirt junior at Louisiana Tech. The left-hander was not drafted. Logan Robbins was undefeated (18-0) as a starter at Jones County Junior College and his only loss at LaTech came in a C-USA contest against USM.
