The Yankees continued their already busy offseason on Tuesday, signing veteran left-handed reliever Matt Thornton to a two-year contract, according to Jack Curry of the YES Network. The deal is worth $7 million, which will be distributed evenly over the two seasons. The club did not confirm the deal.
A 10-year veteran and former All-Star, Thornton will seemingly be called on to fill the void left by fellow southpaw Boone Logan. Logan recently departed the Yankees to sign a three-year deal with the Rockies.
The 37-year-old Thornton joins the Yankees after spending the stretch run last year with the rival Red Sox. Thornton was acquired by Boston from the White Sox in a mid-July trade, though the lefty did not pitch in the postseason during Boston's run to the World Series title.
Thornton finished this past season with a 3.74 ERA over 60 combined appearances between Boston and Chicago. The 6-foot-6 southpaw has limited left-handed hitters to a .233 average over his career, including a .235 mark this past season.
After spending the first two seasons of his career with the Mariners, Thornton had spent the past eight years with the White Sox prior to the July trade. Over those eight seasons, he went 31-35 with a 3.28 ERA while making 512 appearances. That stretch in the Windy City also included three consecutive seasons from 2008-10 in which he posted a sub-3.00 ERA, capped off by his lone All-Star appearance in '10.
In his decade of big league service, Thornton has racked up a 3.53 career ERA over 606 appearances, all but one of which have come out of the bullpen.
