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.
