Vladimir Guerrero partially dislocated his shoulder in the fifth inning on Friday while sliding on his stomach to try to avoid a tag by Dodgers' catcher Jason Phillips. He was attempting to score from first on a double by Steve Finley, and was called out to end the inning. ``It's tough to see something like that happen when he's playing the game hard,'' said Chone Figgins, who drove in three runs with a second-inning triple off Scott Erickson. ``We run the bases hard and we're always aggressive.'' Preliminary X-rays confirmed the jam, and Guerrero's arm was placed in a sling. He was to have a full set of X-rays Saturday in Anaheim before being re-evaluated before Saturday night's game in Los Angeles. ``We're concerned, to say the least,'' manager Mike Scioscia said. ``We need to see exactly what happened and how he feels.''
