Into each season, some lowlights must fall. Mississippi State alum Kendall Graveman experienced one on Wednesday. On in the ninth inning to close out a win for the Chicago White Sox at Colorado, Graveman walked the first three batters and then yielded a two-run, walk-off single. He threw 17 pitches, only five for strikes in the 6-5 defeat. “I just didn’t get the job done,” he told mlb.com. “Obviously, that one’s on me … I’m better than that.” It was his fifth blown save in 10 chances and bumped his ERA to 2.89. He was the fifth reliever called on by manager Tony LaRussa; regular closer Liam Hendriks was down. There have been too many lowlights for the 2022 White Sox, the defending American League Central champs now stuck in third place at 49-49. … DeSoto Central High product Austin Riley saw his 18-game hitting streak end in Atlanta’s ugly 7-2 loss at Philadelphia. He went 0-for-4. The Braves put former Mississippi Braves star Michael Harris II in the leadoff spot for the first time, but the rookie sensation went 0-for-4. … In what apparently was Jacob deGrom’s last rehab start for the New York Mets, he was taken deep by former M-Braves standout Drew Waters, now with Triple-A Omaha in the Kansas City system. Waters, the Southern League batting champ in 2019, might be in line for his first call-up after the Royals’ trade of Andrew Benintendi to the New York Yankees. … Current M-Braves star Vaughn Grissom hit his second Double-A home run in a loss at Pensacola. Grissom is batting .370 in 11 games for Mississippi. … At Low-A Augusta in Atlanta’s system, ex-Mississippi Gulf Coast Community College standout Brandon Parker hit two bombs, giving him nine on the season. The outfielder is batting .288 in his second year at that level. … Add Ole Miss’ Brandon Johnson (Kansas City) and MSU’s Brad Cumbest (Colorado), Jackson Fristoe (Yankees) and Kamren James (Tampa Bay) to the list of MLB draft signees confirmed by mlb.com. Also, former Southern Miss (and Delta State) star Hunter Riggins has signed as an undrafted free agent with the Braves.
