For the second year in a row, the Lowell softball team couldn’t solve Mariko Zumbro.

The Harvard-bound senior pitched a three-hitter as Oakland Tech swept the Transbay Series from the Cardinals with a 10-0 victory at Laney College. Zumbro allowed just three runs on 11 hits in the best-of-three series between San Francisco Section and Oakland Section champions.

“We faced her last year, so we knew what we were up against,” Lowell coach Sascha Ray said. “We were ready for her, but she is just so consistent. She just dominates the game. For the first time this year, we couldn’t hit.”

Ray said it was a dominant offense that carried the Cardinals (21-5) to their regular-season Academic Athletic Association and section titles.

“We hit every pitcher in every game in our season,” Ray said. “It just wasn’t the meat of the order, it was one through nine consistently. I don’t think anyone in our league could hold up to our lineup.”
