Already down, 3-0, with a runner on first and no outs in the second inning on Friday, Anderson slid into the mound hole created by Rangers starter Tommy Hunter, forcing him to fall and throw a wild pitch to Julio Borbon. He was visited by A's trainer Steve Sayles and manager Bob Geren before proceeding to finish the frame -- not before allowing two more hits, a walk and a run, though.
"It's weird, because I'm taller than Tommy Hunter, but his stride's longer and his hole is farther than mine, so instead of landing on the ball of my foot, my knee just locked and I hyperextended it," Anderson said. "I just didn't feel real comfortable after that."
Following the second inning, Geren decided not to further risk damage to Anderson's knee. After all, the 22-year-old hurler has already endured two disabled list stints this year, both due to his left elbow.
"We were just giving him time for it to calm down," Geren said of his mound visit. "We watched him warm up and he looked OK. He finished the inning and then sat down, and at that point we realized it was the right thing to do. I made the decision.
"He was checked out by the doctor. We'll know a lot more tomorrow -- how he feels, if it swells up."
Based on how he felt immediately after the game, though, Anderson didn't appear the least bit worried he won't be ready for his next start on Wednesday in New York.
"It's a little stiff, a little sore," he said, "but it's not excruciating pain -- not any pain, for that matter. Just stiff. ... I have a big bandage on it now, so the movement's limited. I can't really do too much tonight, so we'll see if there's swelling tomorrow and go from there. Right now, all signs point to go for my next start."
Overall, it was a rocky outing for the A's southpaw, who surrendered four runs on six hits and two walks en route to throwing 50 pitches during his pair of innings. It marked his shortest outing since June 3 at Boston, where he left with elbow pain and was subsequently placed on the disabled list.
Anderson's four earned runs put an end to an A's record-tying streak of 18 consecutive quality starts. Furthermore, his two innings pitched halted a streak of 24 consecutive games with six innings or more by the starters -- a mark that was one outing short of tying the Oakland record.
