The A’s lost one right-hander to free agency and another one to a waiver claim, according to the team. Boof Bonser elected free agency after the A’s outrighted him to Triple-A, and the team lost Justin James when the Brewers claimed him on waivers. The A’s also outrighted outfielder Matt Carson to Triple-A, but Carson agreed to terms on a contract with the team.
Bonser logged 25 innings with the A's and Red Sox this year. The 29-year-old posted a 6.12 ERA, but his strikeout (6.1 K/9) and walk (2.9 BB/9) rates weren't bad.
James, also 29, made his big league debut with the A's in 2010. He pitched just 4.0 innings in the majors, but logged 39.1 impressive frames in the upper minors. James posted a 1.83 ERA with 11.2 K/9 and 3.7 BB/9 between Double-A and Triple-A this season.
