"Getting in there, it's the first time I'll get to work in the cage with [hitting coaches] Don Long and Lee Tinsley. That's the final step before taking batting practice on the field," Votto said.
Votto, who is traveling on the road for the first time since he went on the DL for the second time with the quad injury, had been hitting off a tee and taking ground balls for the past several days without issue.
"I definitely feel like I've made tremendous progress," Votto said.
There are two weeks remaining in the regular season, and the Reds are nearing elimination from contending, but the club is still looking for Votto to make incremental progress toward playing. Hitting flips is one more step in intensity that Votto puts on his leg.
"It's day-to-day, station-to-station," Reds manager Bryan Price said. "Everything he's been doing has been increased effort from when he takes ground balls, moving laterally side-to-side, the running -- it's just a progression."
