Peterson is out of the lineup Sunday against the Cubs.
Peterson had made back-to-back starts at second base, but will sit in favor of Chase d'Arnaud for the afternoon contest. The 26-year-old Peterson did manage to catch a break, however, as infielder Daniel Castro was instead chosen for a demotion Sunday when a roster spot was needed to accommodate the activation of Erick Aybar (foot). Even though he remains with the club, Peterson and his .572 OPS will likely be limited to sporadic starts near the bottom of the batting order.
