Twins first baseman Justin Morneau has traveled to Norfolk, Virginia and is scheduled to begin a rehab assignment Friday night with Class-A Rochester. Morneau has been out since June 9, so he will likely need at least a week's worth of playing time with Rochester before coming off the disabled list. Minnesota originally placed Morneau on the DL because of a strained left wrist, but he had surgery June 29 to relieve a pinched nerve in his neck.
