A's outfielder Josh Reddick says he won't be ready for opening day because of his injured oblique, according to an Yahoo.com report.

Reddick played five innings in a minor league game Sunday and reported no issues with swinging a bat, running the bases and sliding.

''It's a huge relief,'' he said. ''I wasn't really worried about anything bothering me, went out there and got a couple of three-ball counts. Swung hard trying to hit it far.''
