The 26-year-old right-hander from the Netherlands has started and come out of the bullpen during his career. He worked parts of four seasons with the Marlins and made seven appearances with the Orioles late last season after the team acquired him.
The Orioles added VandenHurk to the roster as a September callup after he spent much of this season working as a starter with Triple-A Norfolk. He went 9-13 with a 4.43 ERA in 26 starts there.
VandenHurk has made two appearances in relief, but Showalter said the Orioles want to see what he's got.
"It's a good opportunity for him," Showalter said. "I want to see where he is. He pitched real well the last month. Obviously, he looks the part and has a good arm. It's an opportunity; we hope he takes advantage of it."
