Worth noting

• There was sound reason for Neil Walker, who has not played since Wednesday's Grapefruit League opener, missing the start against a lefty (the Rays' David Price) and being down for another off-day Sunday. His right side is a little sore "just from swinging too much."

"We didn't want to push it; [we're] just giving it a couple days to calm down," said Walker, sporting a small ice pack on that side.

Phil Irwin, scratched from his planned Friday outing after experiencing elbow discomfort for a while, will stay down a couple more days before starting a throwing program designed to get him back on the mound. The righty did play some catch Saturday and he is not concerned, dismissing it as a typical Spring Training bump.

Gaby Sanchez experienced discomfort in his right knee, resulting from a slide in Friday's game in Dunedin, Fla., against Toronto, and he was scratched from his Saturday start at first base and in the cleanup spot.

Sanchez is day-to day -- as is Travis Ishikawa, with discomfort in the right hamstring.

• Infielder Chase d'Arnaud, who had been designated for assignment when the Pirates needed roster space for Brent Morel, has cleared outright waivers and been outrighted to Triple-A Indianapolis.
