It has not been smooth sailing for Votto though in the Minors, he is only hitting .205/.347/.359 with an OPS of 706.
It is not surprising at his age but for how good of a hitter Votto is, he should be performing better. That being said, it is only his 15th game back from a serious injury at it takes more than that to get the appropriate amount of reps needed to get back in the swing of things (pun intended).
