Guthrie will stay in KC through the 2015 season.
Bob Dutton of the Kansas City Star breaks down the financial specifics of the new deal:
Terms on Guthrie's new contract with #Royals: three years for $25 million; $5 million in 2013; $11 million in 2014; $9 million in 2015.— Bob Dutton (@Royals_Report) November 20, 2012
The 33-year-old Guthrie had a tough first half with the Colorado Rockies in 2012, but turned things around in July when he joined the Royals' rotation in exchange for fellow right-hander Jonathan Sanchez. The veteran right-hander made fourteen starts for the Royals down the stretch, posting a 3.16 ERA, 1.9 BB/9 rate and 5.5 K/9 rate in ninety-one innings.
Guthrie now has six full big-league seasons under his belt -- all but first half of last season spent in the American League -- and owns a 4.22 ERA and 5.4 K/9 rate in that timeframe.
