Peterson is not in the lineup for Friday's game against the Cardinals, David O'Brien of the Atlanta Journal-Constitution reports.
He will sit for the second time in three days as Gordon Beckham mans second and Ender Inciarte leads off against lefty Jaime Garcia. The 26-year-old Peterson has posted a respectable .753 OPS in 68 games, but the lack of power or speed hurts his fantasy appeal, and the hot-hitting Inciarte could steals more starts in the leadoff spot moving forward.
