Collins, 27, had seen MLB action over the past four seasons with the Tigers. He has had his share of opportunities, but has only managed a .235/.299/.380 slash in 552 plate appearances in the majors.
It seemed that Collins might have a shot at earning some time in the K.C. outfield mix, but he turned in a tepid performance in the Cactus League. And he never got going at Triple-A Omaha, where he has managed just seven base hits — all singles — in his 62 plate appearances.
