Ortiz was optioned to Triple-A Rochester after Sunday's 5-3 loss to the Yankees, Kyle Williams of TheBanner.com reports.
Ortiz was called up to the big-league roster and made his major-league debut Sunday, going 1-for-2 with a double before he was replaced by pinch-hitter Curtis Mead in the bottom of the sixth inning. Ortiz will now head back to Rochester and will await his next chance with the Nationals.
