Johnson to be idled by torn rotator cuff

SAN FRANCISCO – Giants pitcher Randy Johnson learned Tuesday he has a torn rotator cuff in his left shoulder and won't be able to throw for at least three weeks. "Obviously, the first thing I thought is that I won't be able to do my instructional hitting video," joked Johnson, who was hurt while batting in a 7-1 loss to Houston on July 5. Johnson, who was transferred to the 60-day disabled list, is 8-6 with a 4.81 ERA this season but hasn't pitched since the loss to the Astros. After an MRI on Monday, Johnson and team orthopedist Ken Akizuki met. Surgery was not discussed, Johnson said. Also, the Giants placed outfielder Nate Schierholtz on the 15-day disabled list. He strained his left hip when he ran into the outfield fence in Atlanta last week.
