Halpin will start in center field and bat ninth in Sunday's game against the Rays.
The recent return of Angel Martinez from the injured list has yet to cost Halpin playing time, as the 24-year-old will draw an eighth consecutive start Sunday. Halpin turned some heads with a two-homer performance in a July 20 win over the Twins, but he's cooled off since then with just one hit in 16 at-bats over his subsequent five starts.
