Peterson will start at third base and bat seventh Wednesday against the Blue Jays, David O'Brien of The Atlanta Journal-Constitution reports.
It's the second start in a row at the hot corner for Peterson, who will likely be in line for everyday at-bats in the short term after Adonis Garcia (Achilles) was placed on the disabled list Tuesday. Peterson has shown some on-base skills on the past, but beyond offering the occasional stolen base, there's not much to get excited about from a fantasy perspective.
