Peguero was signed by Texas as a Minor League free agent in the offseason, riding a reputation for having tremendous power and a high strikeout rate. He impressed the Rangers in Spring Training by showing significant improvement in his patience and ability to use all the fields.
But Peguero could not consistently duplicate that success at the Major League level after being called up on April 11. He hit .186 with a .310 on-base percentage and a .414 slugging percentage in 30 games and 84 plate appearances. Peguero had four home runs and nine RBIs. He also had 36 strikeouts in 70 at-bats.
