Prado, who singled in the first inning and then grounded out three times, will likely be activated for Tuesday night's series opener against the Nationals. The All-Star second baseman has been sidelined since fracturing his finger while completing a head-first slide on July 30.
Prado initially had some concerns about being able to accurately make the long throws from the third-base position. But as this weekend progressed, he seemed more comfortable about the possibility that manager Bobby Cox may ask him to move to third.
Omar Infante, who has played second base in Prado's absence, and Brooks Conrad are the other top candidates to play third base in the absence of Chipper Jones, who suffered a season-ending knee injury last week.
