However, manager Mark Kotsay’s job is safe.According to MLB.com’s Martin Gallegos, the A’s have dismissed pitching coach Scott Emerson.Emerson was hired as the AL West club’s pitching coach in 2017. Before that, he was the A’s bullpen coach for three seasons.The club’s 5.21 ERA this season is the worst in the American League. The Colorado Rockies are the only team in the Majors with a worse collective ERA (5.44) than the A’s.Sutter Health Park in Sacramento, the A’s temporary home ballpark before their move to Las Vegas, is a hitter-friendly stadium.AdvertisementAdvertisementAdvertisementMORE: What happened to Shohei Ohtani?
