Will prize pitching prospect Taijuan Walker be ready when the regular season starts? Manager Lloyd McClendon remains hopeful, but there now seems to be some doubt.

“I’m not that concerned as we speak,” McClendon said. “I don’t know what’s going to happen in the next week, but we’ll see. I think it’s just a matter of building him (in his endurance) from the shoulder (soreness).”

Walker threw long toss for a second straight day in his ongoing effort to build strength in his once-sore shoulder. He hasn’t thrown from a mound since Feb. 20 but continues to insists he’s fine.

McClendon said, prior to camp, that he’d be disappointed if Walker wasn’t in the rotation when the season started.

“We’ll see where he is in the next couple of days,” McClendon said. “Hopefully, we’ll get him into bullpen (workouts) and building toward getting him back on the mound… Obviously, he’s a little bit behind.”
