Stavinoha, who was with the Cardinals for the second time this season, was hitting .230 with two home runs and 17 RBIs at the time of his demotion.
"I'm in a situation right now where I'm coming off the bench mostly," Stavinoha said before exiting the clubhouse on Friday afternoon. "We have two great right-handed hitters in the starting lineup every day in the outfield, so I'm not going to get many starts here. I'll go down and get some consistent at-bats and try to get it ready in case they need me again.
"I'll go down and just keep working on the things that I was working on here and try to get a little bit more consistent and get on top of the ball, and come back and try to contribute."
Righty Blake Hawksworth, who earned his first Major League win on Wednesday night, appeared to be the choice to be optioned out but was instead kept around as the Cardinals decided they needed an extra pitcher for the weekend series against Houston.
Boggs' stay appears likely to be just one day, as he will be sent back to Memphis on Saturday because the Cardinals won't need a fifth starter in the near future.
"The reality is, we don't need this spot again for 10 days," manager Tony La Russa said. "I mean, I hope he pitches a shutout, but he's probably here today and gone tomorrow. He'll be back later."
Infielder Khalil Greene, on the disabled list with social anxiety disorder, is expected to be activated to the open roster spot.
