"There can't be any clarity right now, because there's no clear-cut closer and we've got a couple guys struggling, trying to find it," Wedge said. "So you mix and match as best you can. That's what happens when you lose your closer, you pull everybody else out of their roles."
Amid Wilhelmsen's struggles, the Mariners have tried Yoervis Medina and Oliver Perez in the ninth. Wedge says that practice will continue as the Mariners start an eight-game homestand.
"It's just part of it," Wedge said. "They've got to handle it, they've got to come together. Opportunities are going to be given like they have been, and it's an opportunity to step up."
