After four-plus seasons of grinding in the low minors, former Hattiesburg High star Joe Gray Jr. received a promotion to Double-A Biloxi on Tuesday. Gray, a second-round draft pick by Milwaukee five years ago, was batting .247 with a homer, 12 RBIs and five steals at High-Class A Wisconsin when the Brewers moved him. Two games into the big jump, he is still looking for his first hit, having started 0-for-9 with four strikeouts in a series at Montgomery. The 23-year-old outfielder, considered a 5-tool player in high school, has fallen off the Brewers’ prospect charts; he is a .212 career hitter though he has flashed some power and speed. It’s time to put it all together. … The Colorado Rockies, currently 11-20, look like a team that could use some help. Maybe they’ve got an eye on what Hunter Stovall is doing at Triple-A Albuquerque. The Mississippi State product is batting .381 in 17 games. He was on base six times in the Isotopes’ 22-4 win over Sugar Land on Wednesday, hitting his first home run of the season, scoring three runs and knocking in two. The middle infielder, 26, is in his fifth year of pro ball. … Jordan Westburg is clamoring for a call-up from Baltimore. The ex-State star went 3-for-5 with a homer and three RBIs for Triple-A Norfolk and is at .337 for the year with six bombs. He has played five different positions this season, though second base might be where he fits best. … Southern Miss alum Chuckie Robinson is batting .414 with three homers and 12 RBIs in 20 games at Triple-A Louisville. If or when Cincinnati needs a catcher, he looks ready for a second MLB stint. … Pitching exclusively out of the bullpen this season, former MSU ace Ethan Small has done solid work for Milwaukee’s Triple-A Nashville club. The lefty, the Brewers’ No. 13 prospect, tossed three scoreless innings Wednesday, trimming his ERA to 2.70 in nine appearances. His brief big league looks as a starter in 2022 didn’t go well, but he’ll get another shot in this new role. … Hoping to become the first Mississippi College alum to play in the majors since Harry Craft in 1942, Blaine Crim just keeps banging in the Texas system. Crim, a first baseman, went 2-for-5 for Triple-A Round Rock in a Wednesday doubleheader to boost his average to .300 with two homers and seven RBIs. He is a .304 career hitter over four minor league campaigns. P.S. Taylorsville native Billy Hamilton, the speedy MLB veteran, is back in The Show with the Chicago White Sox and in two appearances as a pinch runner, he has a run and a stolen base. The White Sox won both games.
