The Athletics selected Kuroda-Grauer's contract from Triple-A Las Vegas on Monday.
In 75 games this season between Double-A Midland and Las Vegas, Kuroda-Grauer has slashed .323/.367/.478 with seven home runs, 15 stolen bases and a 21:29 BB:K. The 23-year-old has mostly played shortstop and second base, but he also has experience at third base and has played a bit in the outfield, as well. Kuroda-Grauer will start at second base and bat ninth Monday versus the Dodgers in his major-league debut.
