Additionally, given that the Rangers already have an All-Star of their own in Adrian Beltre at third base, Texas would want Frazier to play left field, FOX Sports' Ken Rosenthal reports:
Frazier has played 13 games in his career in left field, most recently in 2013. The bulk of his action in left field came in 2012, when he started six games there. Left field was a revolving door for the Rangers in 2015, with nine different players starting at least 10 games there, but none starting more than the 33 Josh Hamilton started.
Playing third base in 2015, Frazier was an All-Star for the Reds, hitting .255/.309/.498 with 35 home runs in 157 games. He was also a finalist for a Gold Glove award for the first time. That followed up a 2014 season that saw Frazier hit .273/.336/.459 with 29 home runs. He was an All-Star in both seasons.
When not at third base, Frazier has primarily played first base, with 83 games and 74 starts there in his career, but the Rangers are set there as well with Mitch Moreland and Prince Fielder, though the latter was mostly a DH in 2015.
There could also be long-term aspirations for the Rangers' interest in Frazier, as Beltre is 36 years old and Frazier is under team control through at least 2017. If Texas thinks they can sign Frazier to an extension, they could make him the heir apparent to Beltre at the hot corner.
