The 22-year-old Davidson made his major league debut last season, appearing in 31 games with Arizona. He hit .237 with three homers. In 115 games with Triple-A Reno last year, Davidson hit .280 with 32 doubles, 17 homers and 74 RBIs.
Arizona selected Davidson in the first round of the 2009 draft, the 35th selection overall.
