The A's optioned catcher Bruce Maxwell to Triple-A Nashville Sunday, the club announced.
Maxwell, 26, went 3-for-4 with two home runs and four RBI in the A's 11-1 win over the Brewers Sunday. Both home runs were his lone of the spring.
In 2016, Maxwell played in 26 games with the A's after his promotion from Triple-A. He hit .283 with one homer.
The 2012 second-round draft pick is a career .266/.346/.370 hitter in the minors with 25 home runs. Maxwell is the A's No. 10 prospect by Baseball America.
The A’s now have 37 players in big league camp.
On the same day the Oakland A's learned they'd be without Jharel Cotton all season, they reportedly reached an agreement with a familiar face to bolster their pitching depth.
Oakland agreed to a one-year, Major League deal with Trevor Cahill pending the results of a physical, according to MLB.com's Jane Lee.
Cahill, a 2006 A's second-round draft pick, 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.
