"The news is bad and may only get worse. An MRI Sunday revealed swelling behind the surgically-repaired right shoulder of Mets starter Chris Young, who was placed on the disabled list for the second time this season.

General manager Sandy Alderson fears this could be an aggravation of a torn labrum that required surgery with San Diego in 2009 and limited him for most of 2010. Alderson does not believe Young will be able to pitch once eligible to return in two weeks. Another doctor will read the MRI today, Alderson explained.

"The question is whether this is a new injury, an aggravation of an old injury or whether it's just an acute response to a chronic condition," Alderson said.

On Saturday night, after his fastball velocity descended into the low 80s during his last start, Young was scratched after failing to get loose. Dillon Gee (2-0, 3.80 ERA) will replace Young in the rotation. Johan Santana was shifted to the 60-day disabled list to make room for left-hander Pat Misch on the 40-man roster.

In four starts, Young (1-0, 1.88 ERA) lasted 24 innings and appeared to be the team's most effective starter. Yet Alderson realized the risks inherent in signing Young. That's why he was able to ink a former All-Star for a base salary of $1.1 million.

"He feels like he's letting us down," Alderson said. "I tried to reassure him that, look, we all understood the risks associated with his signing and his pitching. So this isn't entirely unexpected.""
