November 8, 2024 9:40 AM : Athletics general manager David Forst said this week that the team isn't considering moving Miller back into a starting role, John Shea of the San Francisco Chronicle reports.
Analysis: When the Athletics announced last offseason that Miller would be used as a reliever, they didn't rule out the right-hander eventually returning to the rotation. However, it appears that ship has now sailed and Miller's future is in the bullpen. He was one of the best closers in baseball in 2024, posting a 2.49 ERA, 0.88 WHIP and 104:21 K:BB over 65 innings. Given his past health issues, it's not a surprise that the team has opted to leave Miller in a role in which he's proven he can stay heathy and effective.
