The Mariners announced that they designated left-hander Aaron Laffey for assignment to create roster space for Chance Ruffin, who will be available against the Blue Jays tonight. The Mariners now have ten days to trade, release or outright the contract of Laffey.
Laffey, 26, appeared in 36 games for Seattle this year, posting a 4.01 ERA with 5.1 K/9 and 3.4 BB/9 in 42 2/3 innings of work. The Mariners acquired him from Cleveland this March for cash and Double-A infielder Matt Lawson.
