Masifilo, a 6-foot-3, 270-pound lineman, chose the Cardinal over California and Washington. He also had taken a recruiting trip to Oregon.

"I made my decision on Thursday, but then I talked to my parents and slept on it over the weekend," Masifilo said. "I wanted to make sure I wouldn't change my mind."

Masifilo played offensive line at Campbell but said Stanford plans to have him play defensive end in its new 4-3 scheme. The Cardinal recently hired Jim Harbaugh as their new head coach.

Masifilo had at least 13 NCAA Division I scholarship offers entering this season, including ones from Hawai'i, Arizona, Oregon State and Utah, but he soon narrowed his choices to Stanford, Cal, Washington and Oregon.

Oregon eventually was eliminated from the equation because it does not have a program for his planned major, aeronautical engineering.
