Aaron Miles is being put on the disabled list.
Left-handed relief specialist Neal Cotts, formerly the key set-up man for the 2005 World Champion Chicago White Sox, was optioned to Class AAA Iowa after numerous below-average outings.
Left-hander Jason Waddell was called up to replace Cotts.
Infielder Bobby Scales, who had been unavailable due to severe flu symptoms the last two days, also was optioned to Class AAA.
Shortstop Andres Blanco was brought up from Class AAA Iowa to replace Scales.
With Miles unavailable for at least two weeks, Blanco will play some shortstop to give everyday shortstop Ryan Theriot some time off. Blanco was hitting .314 at Iowa.
Fox has been the hitting sensation of the minor leagues this year, batting .423 with 17 home runs and 50 RBI through Tuesday night.
Manager Lou Piniella mostly likely will use him in the outfield and occasionally at third or first base, although defense has been a question mark for Fox, who's a converted catcher.
