Vance Worley
Career ERA of 3.75. Successful National League experience. And, now, without a home. The 29-year old Vance Worley may be worth a look. In 2016, Worley pitched in 35 games for the Baltimore Orioles, with only four starts. Batters only hit for a .200 average against him as a starter, but his ERA was 4.50 in those games. He was far better out of the bullpen.
However, in 2011, Worley posted an 11-3 record with the Philadelphia Phillies. Sure, that team boasted Roy Oswald, Roy Halladay, Cliff Lee, and Cole Hamels, plus a potent offense, but Worley contributed. That team won 102 games. They look a great deal like the 2016 Cubs.
For his career, Worley is 29-27 with a 3.89 ERA. If the Cubs can get that type of production for him, a $2 million contract for one-year. For comparison, Jason Hammel went 15-10 last year with a 3.83 ERA and was due $10 million in 2017.
