Davis was once again optioned to Triple-A after starting 2010 batting .188 in 15 games (48 at bats). He was recalled on July 9 to play first base for the Rangers. A roster spot, as well as a position in the Rangers starting lineup, became available when Justin Smoak was involved in a trade with the Seattle Mariners for Cliff Lee. On July 29, he was sent back to the RedHawks to make room for Mitch Moreland. In 103 games (398 at bats) with the RedHawks, he had 130 hits, 31 doubles, 14 home runs, and 80 RBI. He finished second in the league in hitting (.327, behind John Lindsey's .353) and fifth in strikeouts (105). He was recalled for the final time on September 11 but this time was used as a backup corner infielder and pinch-hitter, as Moreland was playing first base. In 45 games (120 at bats) with Texas, Davis hit .192 with 23 hits, one home run, and four RBI. He was left off the postseason roster as the Rangers entered the World Series for the first time ever but ended up losing in five games to the San Francisco Giants.
