The Rangers recently called up catcher Sam Huff to fill in for slumping first baseman Nathaniel Lowe, who has an OPS+ of 82 this season. Lowe has not been at his best and is likely to remain at first base. Huff, who has made 59 starts at first base in the minors, is hitting.407 through seven games this season. The right fielder made one error in nine chances.
