Injury news and notes from Wednesday's camps ...
- Pirates second baseman Neil Walker missed Wednesday's contest with back tightness. As a precautionary measure, he's likely to sit out the next two to three games. [CBS Pittsburgh]
- While Orioles second baseman Brian Roberts is able to take part in some low-level baseball activities, he still has no idea when he'll return to game action or even face live pitching after suffering multiple concussions.
"It's still a progression," he said. "We have steps that we're taking, and it's a pretty systematic approach so I don't just go do everything I want every day. My doctor lays out a plan every day, and we kind of go by that. I'm definitely better than I was four months ago, so that's good. It's never as fast as you want, but we're getting there."
