When Shin-Soo Choo was sidelined because of his injuries in September, the Rangers gave Martin a chance to be the everyday leadoff hitter. He has thrived in the role, hitting .319 with a .372 on-base percentage and 13 runs scored in his last 18 games.
"There is still work to do, but his approach is better, at times his swing has been better and his patience has gotten better," Bogar said. "He has used the bunt all year, but now he is using the bunt at the right time. I believe he has a big upside as a leadoff hitter to get our offense rolling next year."
The Rangers also see the potential for a premier defensive center fielder.
"We all know how gifted he is with his speed and his throwing arm," Bogar said. "Now it's time for the next level of focus and play defense the way we expect him to play. Be the general, take charge and run down everything.
"His talent is by far as high or higher than any center fielder that plays in this league. I don't think there's a guy in center field that has the arm that he has. He runs just as fast or faster than all of them."
