Center fielder Alex Rios chose his words carefully Monday while explaining why he didn't talk following Wednesday's promotion of Alejandro De Aza that cut into his playing time.

"Sometimes you got to know when not to talk because you don't want to speak your mind," said Rios, who is batting .207. "Sometimes if you speak your mind, it causes trouble. I'd rather keep it quiet and not cause any disturbance."

When asked if he understood the Sox's decision, Rios took nine seconds before replying.

"I'd rather not comment," he said.

Despite his cut in playing time, Rios vowed he wants to stay with the Sox and salvage a terrible season.
