Nobody doubts that Jake Mangum can put the bat on the ball. After a sluggish start to his pro career, the ex-Mississippi State and Jackson Prep standout is batting .345 over his last 10 games, boosting his average to .252 for short season Class A Brooklyn in the New York Mets’ chain. A fourth-round pick in June, Mangum is rated the No. 24 prospect (by MLB Pipeline) in the Mets’ system. He’s shown off his plus speed, with 11 stolen bases. He has made just one error in 31 games in the outfield, playing mostly center. The question about Mangum is power, which seems to be of utmost importance in today’s game. So far, Mangum hasn’t shown much: five extra-base hits and no homers in 113 at-bats. … Former George County High two-way star Walker Robbins’ switch from hitter to pitcher in the St. Louis system has gone well. The 6-foot-3 left-hander has a 3.95 ERA and two saves in 11 games at rookie-level Johnson City. A fifth-round pick in 2016, he batted .170 over three seasons before going on a pitching program this past off-season. “Hitting’s fun and playing every day is great, but striking somebody out is an adrenaline rush. All eyes are pretty much on you when you’re on the mound. It’s fun.” Robbins told the Johnson City (Tenn.) Press. … Tyreque Reed, the Itawamba Community College product from Houlka, took one step forward and then one step back this season and appears to have regained his footing. Reed began 2019 at high Class A Down East in the Texas system but batted just .216 with four homers in 32 games. He returned to low-A Hickory, where he is hitting .268 with 11 homers in 42 games. Reed batted .267 with 18 bombs at Hickory in 2018, his second pro season. This is a guy who hit .504 with 15 homers at ICC in 2017. … Ex-State star Jacob Lindgren is making progress in his bounce-back season from two Tommy John surgeries. The onetime big leaguer has allowed one run in nine innings at high-A Winston-Salem (Chicago White Sox) and has punched out 13, including four in two innings Thursday. (Ole Miss product Tate Blackman hit a home run for the Dash in that game.) … Southern Miss alum Bradley Roney, also coming back from injury, has an 0.69 ERA in his last 10 appearances for the Double-A Mississippi Braves. He has 27 strikeouts in 17 2/3 innings. … MSU product Nate Lowe was bumped back to Triple-A Durham — despite a .294 average and five homers over 30 MLB games – when Tampa Bay acquired Jesus Aguilar. MLB Pipeline’s Jim Callis predicts that the lefty-hitting Lowe will soon get another call-up, which would be his fourth of 2019. The Rays are an American League wild card contender.
