The Braves and closer Craig Kimbrel have agreed to a four-year extension that includes a team option for 2018 as well, via Jeff Passan of Yahoo! Sports.
As Ken Rosenthal tweets, the extension buys out all three years of arbitration and one, possibly two (with the 2018 option), year of free agency.
Per ESPN's Jayson Stark, the deal is worth at least $42 million over those four years.
In the past three seasons as the team's closer, Kimbrel has a total of 138 saves with an ERA of 1.48, a WHIP of 0.871 and K/9 rate of 14.9 (341 strikeouts in 206.2 innings).
Without question, Kimbrel is the top fantasy reliever heading into the 2014 season.
