First baseman Justin Morneau is expected to have his left arm examined this week. Morneau, bothered most of the year by soreness in his elbow, will likely have an MRI test done Thursday or Friday to examine his forearm for any problems. "He hasn't told me he needs to be shut down yet, so we're playing him," manager Ron Gardenhire said. The Twins anticipated the 24-year-old Morneau anchoring their lineup in his first full major league season, but he went into a slump in mid-May that he never fully escaped.
