The A's fired pitching coach Curt Young on Thursday afternoon, a major shakeup for a team languishing with the worst record in the American League.
Bullpen coach Scott Emerson has been named the new pitching coach, according to a team press release. Gil Patterson, who has been the team's minor league pitching coordinator, will serve as bullpen coach for this weekend's series against the Yankees, with no word on a permanent replacement for that role.
The Athletics' 4.83 team ERA ranks 13th in the American League, though their pitching staff has also been hit hard by injuries.
Young has been a fixture in the A's dugout, serving as pitching coach for the past 16-plus seasons, minus a one-year departure to serve the same role for Boston in 2011.
Emerson has coached in the A's organization since 2003, most of that time in the farm system. That makes him very familiar with not only current A's pitchers but many of those coming up through the minors as well.
UPDATE (Mar. 19, 7:45 p.m. PT): The A's officially announced the Cahill signing on Monday. This story has been updated to reflect that.
On the same day the Oakland A's learned they'd be without Jharel Cotton all season, they signed a familiar face to bolster their pitching depth.
Oakland agreed to a one-year deal with Trevor Cahill, nearly 12 years after the A's drafted him in the second round.
Cahill pitched for Oakland from 2009-11. He started 96 games in three seasons with the A's, going 40-35 with a 3.91 ERA and 1.32 WHIP. Since Oakland traded him to the Arizona Diamondbacks in Dec. 2011, Cahill's pitched for six teams.
The 30-year-old won a World Series ring with the Chicago Cubs in 2016, and pitched for the San Diego Padres and Kansas City Royals last season. In 2017, he went 4-3 in 21 appearances (14 starts) with a 4.93 ERA and 1.62 WHIP.
The A's will be without starting pitcher Jharel Cotton for the entire 2018 season as he is set to undergo Tommy John surgery.
Cotton, 26, went 9-10 with a 5.58 ERA in 2017 after a rookie season in which he went 2-0 with a 2.15 ERA in five starts. Leading up to the injury, he was 0-1 with a 3.75 ERA over four appearances in spring training.
