Texas Rangers CF Craig Gentry is a “young” player in that he has limited major-league experience. Gentry, 29, has never had more than 240 at-bats in a major-league season. That should change this year. The Rangers will go with the two-headed center fielder of Leonys Martin and Gentry to replace Josh Hamilton, who moved to the Los Angeles Angels as a free agent. Martin and Gentry have each played well this spring. “I’ll have two of the greatest heads out there you’ve ever seen,” manager Ron Washington said. Washington called Gentry the biggest surprise of the spring for his offense and aggressiveness on the base. New hitting coach Dave Magadan is drawing more power from Gentry. He tripled off the center-field wall in the first inning of the win against Cincinnati and has eight extra-base hits in 51 at-bats this spring. Gentry has 24 extra-base hits in 423 career major-league at-bats. The Rangers also have not had to prod Gentry to run, as they have in the past. He stole second to set up a run in the fourth against the Reds and has succeeded in all six tries. “He’s figured out just how good he can be and is just letting it go,” Washington said.
