The Athletics acquired Tarnok alongside Kyle Muller, Manny Pina, Royber Salinas and Esteury Ruiz in a three-way deal Monday which sent Sean Murphy and Joel Payamps to Atlanta and William Contreras and Justin Yeager to Milwaukee, Robert Murray of FanSided.com reports.
Tarnok was one of the Braves' top prospects and will be one of Oakland's now. The right-handed pitcher posted a 3.68 ERA and 49:17 K:BB in 44 innings with Triple-A Gwinnett last season. He also made 15 appearances in Double-A and one game -- his big-league debut -- with Atlanta in August.
