Worried about Webb?

If you own Brandon Webb, there's a decent chance he's your No. 1 starter.

He didn't pitch like it on Opening Day.

Webb gave up six runs on six hits in only four innings Monday before leaving with shoulder stiffness in the Diamondbacks' 9-8 win over the Rockies. Now he's going to skip his next start, although no medical tests are planned yet. It sounds like manager Bob Melvin is just being cautious:

"For a guy like him, this isn't something you can mess around with. I'd hate for him this early in the season to go out there and pitch with some soreness already, or some stiffness."

Webb has made at least 33 starts the past five seasons and has been a model of consistency, so it's not like there were any warning signs. Right now I'd just keep my fingers crossed and hope this is just a false alarm.
