CHICAGO — The Chicago Cubs and left-hander Brian Duensing have agreed to a one-year contract, giving manager Joe Maddon a versatile new reliever for the bullpen.

The reigning World Series champions also offered 2017 contracts to right-handed pitchers Jake Arrieta, Justin Grimm, Hector Rondon and Pedro Strop.

Duensing's contract is for $2 million, according to a person with knowledge of the deal. The person spoke on condition of anonymity because the team did not disclose terms Friday.

Duensing went 1-0 with a 4.05 ERA in 14 relief outings for Baltimore last season. He pitched the previous seven seasons with Minnesota.

For his career, he is 42-37 with a 4.13 ERA in 368 appearances, 307 of which have come in relief.

Chicago has holes to fill in the bullpen this off-season, and Duensing could help. Left-hander Travis Wood and righty Trevor Cahill, two effective relievers with starting experience, became free agents along with right-hander Joe Smith and closer Aroldis Chapman.

Left-handed pitchers Gerardo Concepcion and Zac Rosscup, right-handed pitcher Conor Mullee and infielder Christian Villanueva were non-tendered on Friday.

Chicago's 40-man roster stands at 35 players.
