Barton exits with left hamstring strain

SCOTTSDALE, Ariz. -- A's first baseman Daric Barton exited Saturday's game after just one inning because of a left hamstring strain.

Barton suffered it in his first at-bat and is likely to be held out of baseball activities come Sunday.

"You would think," manager Bob Melvin said. "Hamstrings aren't something you want to mess around with. To what degree he strained it, I'm not sure."

Barton was considered likely to make the Opening Day roster as the second first baseman, but that could easily change should he miss an extended period of time. Most hamstring issues typically require at least a couple of weeks of rest.
