Hudson lasted just 1 2/3 innings while allowing six runs in his start last Friday, and his turn in the rotation is not up again until Thursday's finale with the Rangers.
"It stinks," Hudson said. "We won the game, which is the most important part, but I've never thrown under two innings before in my career, so to just sit around for six days with the off-day and think about it is kind of tough."
Hudson has hardly just been sitting around, though. He threw his normal between-start bullpen session Sunday, and because he has an extra day between starts this time around, he threw another shorter bullpen session Tuesday.
Still not satisfied with where he was at, Hudson was in the visitor's bullpen by himself Wednesday afternoon going through his windup and follow through without a ball.
"Doing stuff without a ball sometimes helps you just get back to basics, and all of a sudden something can click from there," Hudson said. "I don't know if it's going to work or not, but I figured I would give it a try and see if I could figure something out."
Hudson missed six weeks due to an impingement in his shoulder and pitched well in his first two starts after being activated from the disabled list.
Then came Friday's debacle, which has spoiled the last five days for him.
"I got pretty gassed there towards the end, and stuff was coming back over and running up and away," Hudson said of that outing against the A's. "I just couldn't make a pitch and get out of it. It is what it is. It's just a bad start and my teammates picked me up."
