The 6-foot, 170-pound left-hander was 4-0 and had 50 strikeouts in 28 2/3 innings last season for the 25-9 Marauders.
James, who competed in the North-South series and Area Code games this summer, is a Pac-12 caliber pitcher, according to Jesuit coach Joe Potulny.
But Potulny says James has an even bigger upside.
"He's a stud academically," Potulny said. "Whatever he does as an athlete will be great, but he's someone who gets it done in the classroom. Stanford is a pretty good deal."
James will be the second player during Potulny's tenure to play for Stanford. Catcher Damien Alvarado played for the Cardinal from 1996 to 2000.
James is the third player from the 2012 Marauders to verbally commit, joining shortstop Zach Green (Oregon State) and second baseman Louie Mejia (Pacific).
