OAKLAND -- A's left-hander Brett Anderson took another step Tuesday in his recovery from Tommy John surgery when he threw his first full bullpen session, using all his pitches.
Anderson said on Wednesday that he expects to take an even bigger step in the next week or two.
"I'm going back to Arizona in a couple hours," Anderson said before the A's game against Kansas City. "And I'm going to stay there for a while, because I'm going to start throwing live BPs here pretty soon, I think. Guys don't want to come in at 11 o'clock to face live BPs when they've got to play 162 games."
Anderson will throw his next bullpen session on Friday at the A's Spring Training headquarters in Phoenix and begin throwing live battling practice to Minor Leaguers in "the next week or two."
"Get some warm weather and some younger guys so I can face them at my disposal," Anderson said.
Anderson underwent Tommy John surgery on July 14, and he's on track to return in mid-July.
"His [bullpen sessions] have really been terrific," A's manager Bob Melvin said. "I've said often in Spring Training, if you were to watch him throw, you'd think he was rehabbing something else. He's got the potential to be the top-of-a-rotation starter, and we probably look for that when it's almost like a trade, a midseason trade when he comes back. We're not trying to put an exact timetable to speed him up or anything, but he's doing beautifully at this point."
Anderson said he's not surprised that he's making such good progress.
"Tommy John's kind of a cut-and-dried deal, hopefully, for the most part," Anderson said. "If you do the rehab and you do the work, you're going to come back. I've been step for step right now. Hopefully there's no setbacks, but just follow the daily plan, and I've been feeling good. That's the goal."
