River Mahler brings proven power-speed production and elite infield pedigree to Stanford
River Mahler is a high-impact Stanford infielder whose game is built on a rare blend of contact quality and extra-base pop; in 2026 she is hitting .351 with a .398 on-base percentage, and her prep résumé included a .691 batting mark with 9 home runs, 6 triples, and 18 doubles in a record-setting season. Beyond the numbers, she has been identified as a national-level prospect and All-American-caliber talent, which suggests she offers both immediate lineup value and a competitive edge in the infield.
