2023 Oakland Athletics season

The 2023 season was the 123rd season for the Oakland Athletics franchise, and the 56th in Oakland. The Athletics failed to improve on their 60–102 record from the previous season, going 50–112. They started 10–45 in their first 55 games, which tied them with the 1904 Washington Senators and 1899 Cleveland Spiders for the worst 55-game start in MLB history and with a 21–60 first half, were on pace to tie (and at some points in the season, break) the record for most losses in a season in the modern era set by the 1962 Mets before having a 29–52 second half to avoid breaking the record.

Seasons

With their loss on August 8, the Athletics became the fastest team to be guaranteed a losing season since the 2003 Detroit Tigers, who lost 82 of their first 111 games. Despite the MLB adding an additional wild card spot to its playoff field, the Athletics, on August 23, after their loss to the Kansas City Royals, were eliminated from postseason contention, becoming the first team eliminated, as well as the fastest playoff elimination since the 2018 Baltimore Orioles, who were eliminated from playoff contention on August 20, 2018 which was surpassed next season by the 2024 Chicago White Sox.

Although the Athletics showed signs of improvement in the second half of the season, they still became the first team since the 2019 Detroit Tigers to lose 111 or more games, en route to finishing 50–112. The A's finished last or close to last in the American League and in MLB in most batting and pitching categories this season.

The Oakland Athletics drew an average home attendance of 10,275 in 81 home games in the 2023 MLB season. The total attendance was 832,352.

Offseason

Coaching changes

On November 7, 2022, the Athletics announced that bench coach Brad Ausmus would not return for the 2023 season. On November 28, the club announced that Darren Bush would be promoted from third base coach to bench coach. The A's also announced that Eric Martins would move over from first base coach to third base, as Mike Aldrete takes over as first base coach. Oakland also named Mike McCarthy as bullpen coach.

Rule changes

Pursuant to the CBA, new rule changes will be in place for the 2023 season:

• institution of a pitch clock between pitches;
• limits on pickoff attempts per plate appearance;
• limits on defensive shifts requiring two infielders to be on either side of second and be within the boundary of the infield; and
• larger bases (increased to 18-inch squares);
