Hudson pitched in an extended spring game on Thursday, and he will do so again next Wednesday. It's possible he could then head out on a rehabilitation assignment.
"Just depends on how I bounce back," Hudson said. "It's just day by day at this point. Just see how I feel and go from there. There's really no set schedule, except for when I'm supposed to throw. And if need an extra day, we'll take an extra day, or if I need an extra five days, we'll take an extra five days."
So far, Hudson has not experienced any setbacks or needed extra time, but he's careful not to get ahead of himself.
"Pretty excited, but I've still got a little ways to go," Hudson said. "I just try not to look at it too much and just concentrate on getting better and hopefully getting my command up to par to where I need it to be to be competitive up here and get my arm strength and stamina up."
Hudson, who threw 70 pitches Thursday, is becoming more comfortable with the small tweaks he has made to his mechanics. The changes, he hopes, will take some of the stress off his elbow and shoulder.
"I just feel like I'm getting on top of the ball better and working downhill better," Hudson said.
