"I'm guessing probably Sunday," Reds manager Dusty Baker said. "He said he feels better, but he still feels it. And that's not under competition with a real good fastball where he has to rotate. He'll probably tell me [Saturday] or [Friday]. Whatever they tell me, I usually add a day or two."
Like on Thursday at Toronto, Jerry Hairston Jr. played shortstop while Jeff Keppinger shifted over to third base.
Encarnacion hasn't played since he exited early from Sunday's game at New York when his back locked up after a leaping catch.
In other injury update news, right-handed starter Josh Fogg worked a complete game in his rehab assignment outing for Triple-A Louisville. Facing Rochester, Fogg allowed four runs (three earned) on 10 hits with one walk and six strikeouts in a 4-1 loss.
Fogg has been on the 15-day disabled list since June 1 and began his rehab assignment June 11. He made his first three starts with Class A Sarasota before moving up to Louisville.
"I told him I wanted him to go to Triple-A and have two [starts] with better competition," Baker said. "Then we'll make a decision from there."
