A's relievers Chafin and Diekman become free agents

Andrew Chafin

This could be a long offseason for the Athletics. Their longtime manager Bob Melvin already has left for the San Diego Padres, and on Thursday, two of their most-used relievers are officially headed for free agency. 

The A's declined the 2022 option on left-hander Jake Diekman's contract, sending him to the open market. Oakland exercised the 2022 mutual option on lefty Andrew Chafin's contract, however, Chafin declined. He too is now a free agent. 

Chafin was acquired by the A's from the Chicago Cubs on July 26 for Greg Deichmann and Daniel Palencia. In 28 appearances out of the bullpen for the A's, Chafin went 2-2 with a 1.53 ERA. Between the A's and Cubs, he had a 1.83 ERA over 71 games and 68 2/3 innings. 

Lefties hit just .170 with a .223 slugging percentage against him.

Diekman was acquired by the A's from the Kansas City Royals at the 2019 trade deadline. In his two-plus seasons in Oakland, he appeared in 116 games and had a 3.25 ERA. Diekman allowed only one earned run in 21 1/3 innings in the 2020 shortened season. 

But his ERA raised to 3.86 this season for the A's. 

As they search for a new manager, the A's have a handful of free agents to handle and their roster could see plenty of changes in the coming months.
