According LaVelle E. Neal III of the Minneapolis Star-Tribune, the Twins have designated right-hander R.A. Dickey for assignment in order to clear roster space for newly acquired reliever Ron Mahay.
Dickey, a knuckleballer who turns 35 in October, had a 4.62 ERA, 1.62 WHIP and 42/30 K/BB ratio in 64 1/3 innings with the Twins this season. He has a 5.43 earned-run average in 442 2/3 career innings. With those numbers, there's a good chance he'll land back at the club's Triple-A Affiliate in Rochester, New York.
