Robert Murray of Fansided reports that the Nationals are close to an agreement on a contract extension with right-hander Cade Cavalli.

The 28-year-old hurler has blossomed into the Nationals’ ace this season, going 12-5 with a 3.12 ERA, 1.17 WHIP and a 194/48 K/BB ratio across 164 2/3 innings. Cavalli is currently in the first of four arbitration years as a Super Two player, so it seems likely that the extension would cover all arbitration years and the first year or two of free agency as well.
