COLLEGE STATION, Texas (Interstat) — Southern California’s offense erupted for 19 runs on 19 hits Saturday evening, routing Lamar 19-6 in an NCAA Division I Baseball Championship playoff game at College Station.

The Trojans (44-16) wasted no time building a massive lead. In the top of the first inning, first baseman Adrian Lopez homered to left-center, driving in two runs, and left fielder Andrew Lamb followed with a three-run homer to right-center, giving USC a 5-0 advantage. The Cardinals (34-27) managed a single in the bottom of the inning but could not score.

Southern California added three more runs in the second. Center fielder Walter Urbon doubled and scored on Lopez’s double to right-center. Lopez later scored on a single by designated hitter Au. Lopez, and the Trojans led 8-0.

The offensive barrage continued in the fourth. Catcher Cade singled, advanced on a wild pitch, and scored on Lamb’s single. After Lamb and shortstop Carpentier each reached base, Urbon crushed a grand slam to left field, scoring four runs and extending the lead to 13-0.

Southern California tacked on five runs in the fifth, taking advantage of a Lamar error. Takeuchi doubled and scored on Cade’s double, and Cade later scored on a fielding error by the shortstop. Basseer reached on the error, scoring on Carpentier’s double, and Urbon’s sacrifice fly brought home Lamb. The Trojans led 18-0.

Lamar finally broke through in the bottom of the fifth. Back-to-back walks and a single by Taylor produced two runs, and a double by Wagoner drove in another. A bases-loaded walk to Ben made it 18-5 before reliever Chase Herrell ended the inning.

Southern California added a run in the sixth when Takeuchi doubled and scored on Cade’s single, making it 19-5. Lamar scored its final run in the bottom of the sixth on a throwing error by the third baseman.

The game’s most important sequence was USC’s early onslaught, which effectively decided the outcome before the Cardinals could mount any response. The Trojans sent 10 batters to the plate in the first inning alone, highlighted by Lamb’s three-run homer. That early five-run cushion allowed USC’s pitchers to work with confidence, though starter Mason Edwards struggled with command, allowing five earned runs on no hits over 4 1/3 innings. Four relievers combined for 4 2/3 scoreless innings, with Rohan Kasanagottu striking out three in the eighth and Henry Chabot striking out two in the ninth.

Walter Urbon was the top star for Southern California, going 5-for-5 with a home run, a double, and five RBIs. The performance was a dramatic turnaround for Urbon, who had gone 0-for-4 against Texas State on Friday and was hitless in two of his previous three games. Adrian Lopez added three hits, including a home run and a double, driving in four runs. Andrew Lamb had two hits, a home run, and four RBIs. Isaac Cadena went 3-for-3 with two RBIs.

For Lamar, starter Blayne Fritcher pitched a scoreless inning of relief but the damage was done early. The Cardinals managed only six hits, with Tracy, Taylor, Wagoner, and Evans each providing key knocks.

The victory sent Southern California into the next round of the NCAA tournament with momentum after a 4-5 loss to Texas State on Friday. Lamar’s season ended at 34-27 following a 7-5 loss to Texas A&M on Friday.
