"I want to play," he said. "It's tough to just sit here. Your health is obviously more important. I've got to show that I can get healthy and hopefully get back out there."
Springer is taking batting practice, but he said the issue at this point is making sure he won't reinjure the quad when he gets to game speed, which can't be simulated. Thus, he's taking it slow.
"I have to be smart about it," he said.
Springer said he didn't know if he would have to be sent back out on another Minor League rehab assignment to prove he's healthy enough to play at the Major League level.
"If that's what it takes to make sure I'm OK, that's what I'll have to do," he said.
Astros manager Bo Porter said he's not concerned Springer isn't yet playing.
"He has some discomfort and we're just going to have to weigh all the options and just continue to monitor him as we move forward," he said. "Let him continue with the course in which the trainers are taking, and if this becomes something of more length, we'll revisit [a Minor League rehab assignment] at that time."
