Oakland Athletics General Manager David Forst will not return to his position, with the team announcing Friday that both sides have "mutually agreed to part ways." The team has not yet named a permanent replacement, but Assistant General Manager Dan Feinstein will serve as interim GM for the remainder of the season.

"David has been an integral part of the A’s and our success for nearly three decades," team owner and managing partner John Fisher said in a statement. "His leadership, dedication, and commitment to this team have helped shape our baseball operations department and position us for the future. We are grateful for everything David has done for our organization."

Forst had been the general manager since 2015 and joined the organization in 2000. His contract was extended last September for the current season. The decision comes as the Athletics are in the midst of a transition, with the franchise awaiting a planned relocation to Las Vegas in 2028. The team currently sits near the bottom of the American League West standings with a 45-70 record.

"It was truly an honor to spend the last 27 years with the A’s, especially the last 11 as the GM," Forst said in his own statement. "This organization is full of incredibly talented, devoted, and good people, and I am lucky to have worked alongside them for so long."
