"I have been a leadoff hitter all my career in Cuba," Martin said. "I'm ready. I want to show them I can get on base and score some runs."
Manager Jeff Banister said Martin will be considered although Choo is healthy again. Martin's speed suggests he belongs at the top, but Choo gets consideration because of his high on-base percentage. Elvis Andrus has also hit there in the past.
There have been 50 American League players who have had 300 plate apperarances in the leadoff spot over the past two years. Of those 50, Choo has the highest on-base percentage at .403. Martin is 27th with a .329 on-base percentage.
Martin has speed, stealing 31 bases last season, which was tied for the fifth most in the AL. But his success rate of 72.1 percent was 21st among 25 players with 16 or more stolen bases.
"I have been working on my baserunning, working on getting better jumps," Martin said. "I also have to focus on covering the strike zone and swinging at strikes. That's the key to leading off. I want to learn from Choo how he keeps his concentration all through the at-bat."
He still has to prove he can be a leadoff hitter. Banister has not committed to any set lineup although he admitted that Martin has the skills identified with a leadoff hitter and Choo has the ability to hit anywhere in the order.
"I'm glad he wants to be the leadoff hitter," Banister said. "I hope he takes that approach all spring. My message to him is show up with that attitude every single day. Show up having the desire to be the leadoff hitter.
"There is some responsibility that goes with being a leadoff hitter. He is the first guy that goes up there every night and sets the tone for the rest of the night. It's an opportunity to get the offense going and you're hitting among the best hitters in the lineup."
