The Yankees claimed left-hander Aaron Laffey off of waivers from the Mariners and designated catcher Gustavo Molina for assignment, according to Mark Feinsand of the New York Daily News (on Twitter). It's the second time this week that the Yankees have claimed a left-hander; they picked up Raul Valdes on Tuesday.
The Mariners designated Laffey for assignment to create roster space for Chance Ruffin earlier in the week. Laffey 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 the 26-year-old from Cleveland this March for cash and Double-A infielder Matt Lawson.
To create room for Laffey on their full 40-man roster, the Yankees designated Molina, who wasn't with the Major League team. The 29-year-old has spent most of the season at Triple-A, where he has a .239/.273/.310 line in 152 plate appearances. He also appeared in three Yankees games this year and has previous experience with four other MLB teams.
