Doubront agreed to a one-year, $1.925 million deal with the Cubs on Thursday, Bruce Miles of the Daily Herald reports. The deal allows both sides to avoid arbitration, and the 27-year-old will return to Chicago, where he landed after a late-July trade with the Red Sox. In four starts with the Cubs, Doubront went 2-1 with a 3.98 ERA across 20.1 innings. Despite the small sample size, it was a noted improvement over his performance with Boston, where he went 2-4 with a 6.07 ERA in 17 appearances (10 starts, 59.1 innings).
