Kansas City, MO (SportsNetwork.com) - The Kansas City Royals have signed reliever Jason Frasor to a one-year deal with a mutual option for 2016.

Frasor will reportedly earn a base salary of $1.25 million in 2015 with a $2 million option for the 2016 campaign. There is also a $500,000 buyout in the pact.

The 37-year-old Frasor came to the Royals in a mid-July trade from Texas and excelled, allowing just four earned runs in 23 innings, including the postseason.

Frasor pitched in seven of the Royals' postseason games, going 2-0 with a 1.69 ERA and earned the victories in the wild card game against Oakland and in Game 3 of the American League Championship Series against the Orioles.

The right-hander has pitched to a career 3.59 ERA over 647 games out of the bullpen with the Toronto Blue Jays, Chicago White Sox, Rangers and Royals. His 34 victories out of the bullpen are also tied with the Los Angeles Angels' Huston Street for fourth among active big leaguers.
