Giants' Johnson has torn rotator cuff

Randy Johnson has a torn rotator cuff and won't be able to throw for the San Francisco Giants for at least three weeks. San Francisco manager Bruce Bochy said Tuesday the 303-game winner had an MRI on his injured left shoulder Monday and the test showed some tearing. The 45-year-old Johnson is 8-6 with a 4.81 ERA with the Giants this season but hasn't played since injuring himself while batting during a 7-1 loss to Houston on July 5.
