Rengifo is expected to begin the campaign with Triple-A Salt Lake, Rhett Bollinger of MLB.com reports.
Rengifo entered spring training with a chance to earn a roster spot as a backup infielder, but he struggled in Cactus League play, hitting .240 with only one extra-base hit (a double) in 25 at-bats. Per Bollinger, Rengifo is unlikely to break camp with the Angels; instead, he'll gain more seasoning with an everyday role at the Triple-A level.
