De Aza carries a .289 average following his start in right field during Thursday's 4-2 loss to the Indians and has provided a strong presence in the lineup's two-hole.
De Aza, 27, is in his 10th professional season, but he had just 194 Major League at-bats prior to 2011. The left-handed hitter doesn't attribute his success to any significant changes to his approach at the plate.
"Just timing. I started working hard on my timing at the plate," De Aza said. "Before, I tried to rush right across the ball. Now, I just try to use my hands and use my speed.
"I don't feel pressure. I just try to play the game the right way. And hopefully good things can happen, you know."
Ozzie Guillen knows De Aza from their Marlins' days together, and the skipper likes the lineup flexibility he provides. Guillen also likes that De Aza can execute the hit-and-run or swipe a base at the top of the order.
"Now he's got a shot to play, I don't want to say every day, most of the time," Guillen said. "I hope he continues to play like that."
