Cubs' Chris Flexen: Officially added to roster

The Cubs selected Flexen's contract from Triple-A Iowa on Wednesday, Maddie Lee of the Chicago Sun-Times reports.

Flexen altered his arm slot before posting a 1.16 ERA and 21:8 K:BB over 23.1 frames covering five starts with Iowa. The righty will work as a long reliever for now, but making starts at some point this year is possible if he pitches well.
