Rodriguez, whose 534 career home runs ties Jimmie Foxx for 14th place on baseball's all-time list, is the leading vote-getter at his position on the American League All-Star team.
"I've worked hard for my swing and I definitely don't want to let anything get in the way of it," he said Tuesday on the Yankees' Web site. "It's always been (a concern) for me (and) my only responsibility this year is to the New York Yankees."

Abreu added that "it took a long time" to get his normal swing back.
