Some bad news this morning out of Pirates camp.
According to beat writer Michael Sanserino of the Pittsburgh Post-Gazette, right-handed starter Jeff Karstens has been scratched from his scheduled Grapefruit League outing Sunday against the Orioles because of “continuing shoulder discomfort.”
Karstens reported feeling soreness in his right shoulder on February 19 — after one of his first throwing sessions of the spring. It was manageable for a while but is now causing him great discomfort. He will open the 2013 regular season on the 15-day disabled list, without a mapped-out return timetable.
Karstens posted a 3.97 ERA and 1.15 WHIP in 90 2/3 innings last season while fighting hip and shoulder injuries. Jeff Locke, Jonathan Sanchez, Kyle McPherson and Jeanmar Gomez are fighting for his spot.
