SAN FRANCISCO -- An MRI performed Monday revealed a slight muscle tear in Aaron Rowand's right (throwing) forearm, forcing the Giants' leadoff hitter to miss his seventh straight start as his team faced the Pittsburgh Pirates at AT&T Park.
Rowand said he planned to take two days of rest and continue receiving treatment. The injury doesn't affect his ability to swing the bat -- he's pinch-hit three times in the past six games -- but throwing remains an issue.
Andres Torres assumed Rowand's slot in the lineup Monday against the Pirates.
Rowand said he felt his arm swell up after he was hit by a Tommy Hanson pitch on July 20, but that it was exacerbated by throwing later in the game.
Prior to Monday's series opener against the Pirates, manager Bruce Bochy said placing his starting center fielder on the 15-day disabled list was not yet a necessity.
Rowand added: "They don't want to put me out there in a game situation where, [with] the adrenaline flowing ... [I] end up hurting it longer and spending more time out."
The outfielder, who is one hit from 1,000 for his career, said he hoped to start throwing the baseball in a couple of days. Then he knuckled his head and said "knock on wood" when explaining his rosy outlook.
In other injury news, Randy Johnson told reporters he would discuss the details of his own MRI with Dr. Ken Akizuki during Monday's game. The Giants placed Johnson (strained left shoulder) on the DL on July 6.
"Now I'm at the point where I feel pretty good," said Johnson, who has been working out in Phoenix six days a week to strengthen his rotator cuff and the surrounding area. "There's times when it aches a little bit, but I feel relatively good. What does that mean? I don't know because I haven't picked up a ball since the last pitch I threw against the Houston Astros [on July 5].
"I'm hoping [I return] sooner rather than later. I'd like to be a contributor, obviously."
Furthermore, infielder Emmanuel Burriss will begin to rehab his broken left foot in three to four weeks. Greeting teammates in the clubhouse Monday, Burriss said he's looking forward to playing winter ball.
