The concept of a ground ball pitcher IMO is a guy who gets a lot of outs on the ground and does not allow many homers. Such a pitcher usually can't get away with 23 homers at this point in the season.
You avoid homers by giving up fewer fly balls. You don't have a ton of influence over your HR/FB rate. Perhaps a little, but not much. Most guys generally hover around 10-11%.
He's giving up almost 2 grounders for every fly ball. If he were giving up a normal rate of homers to fly balls, that number would be in the range of 13-15 homers which is why his xFIP is 3.71. Latos, despite his strikeouts, has an xFIP of 3.83.
