Andrew McCutchen, the Pirates' center fielder, has a mildly sprained AC joint in his right shoulder after a diving catch Sunday, and he might miss some playing time early this week.
McCutchen was injured in the eighth inning of the 9-0 shutout of the Houston Astros at PNC Park, diving to rob Pedro Feliz of a hit in shallow right-center, then rolling over hard onto the shoulder. In visible pain, he quickly got up and began walking toward the home dugout.
X-rays did not detect a fracture, and no MRI was scheduled.
Manager John Russell did not rule out that McCutchen could return as soon as tonight, but he cautioned that "we'll take a look when he gets here in the afternoon."
The AC joint is at the top of the shoulder, and more serious versions of the injury are called separated shoulders. There was no indication this was that serious.
McCutchen said he knew he would not be able to swing a bat right after it happened.
Of the play, he said, "I made a late dive and really didn't get myself set. I felt it right away. It hurt."
Russell praised McCutchen for the extra effort with the Pirates up, 6-0, late.
"He left it all on the field," Russell said.
"Just a play, man," McCutchen said. "I've got to make the play, doesn't matter what the score is."
McCutchen has missed only one game all season, that on May 4 after he mildly sprained his ankle two days earlier in Los Angeles.
