Ishikawa left Sunday's Cactus League game with a back injury, and he will be reevaluated Monday, Andrew Baggarly of the San Jose Mercury News reports. The injury doesn't sound overly serious, but with Opening Day only a week away, Ishikawa doesn't have much time to recover. If healthy, he'll likely make the Opening Day roster, as Hunter Pence (forearm) is expected to miss at least the first few weeks of the season.
