The Grambling State baseball team suffered a 12-9 loss to Southern on Sunday at Wilbert Ellis Field at R. W. E. Jones Park, concluding a three-game series sweep to the Jaguars. For the first time this season, GSU (12-20 overall, 9-5 SWAC) was swept in a SWAC series. It also marked the first time that Grambling State was swept by Southern (16-15, 10-3 SWAC) since 2021. As was the case Saturday, the Tigers were able to hit the ball well, but inconsistency on the mound doomed GSU. For the second game in a row, Grambling State issued double-digit walks, with the Tigers walking 12 batters in the series finale after 18 on Saturday. Starting pitcher Carlos Peguero ( 1- 8) was charged with the loss after giving up eight runs on seven hits in three innings pitched. He struck out three batters and walked five. GSU outhit Southern 12-10, with Cameron Bufford leading the way by going 2-for-5 with 2 RBI.
