Votto has been out of the lineup since July 16 with a meniscus tear in his left knee but has begun baseball activities recently -- throwing, catching, hitting and doing some light jogging.
Reds manager Dusty Baker said Votto is "right on schedule," and the All-Star first baseman will travel with the team this week to Milwaukee and Chicago.
"He's progressing. He's going to go on the road trip with us," Baker said. "He's hitting, he's fielding some right on the bag, he's throwing. The real test is going to be running, cutting and sliding. He's not quite at that point yet. But he's on the way."
While Votto has been out with a tear, the Reds have been on a tear, winning 16 of 19 since his absence.
Baker said Votto has been working hard every day since his July 17 surgery, and the former National League MVP has earned himself a day of rest.
"I gave him off [Sunday]," Baker said. "He's been working around the clock trying to get ready. Sometimes you can overwork a guy. Let your body rest. I told him don't come in today, because if he's here, he's going to work. He's probably working where he is anyway."
