Ruiz (head) will start at catcher and bat eighth Saturday against the Nationals, Mark Zuckerman of NatsJournal.com reports.
Ruiz will return to the starting nine for the first time since taking a foul tip off his mask during Wednesday's game against Atlanta. The 28-year-old has been productive when in the lineup recently, slashing .348/.411/.470 with two homers, nine RBI and eight runs scored across 73 plate appearances since the beginning of August.
