Not only home field, but Sonny Gray and Pablo Lopez on full rest for 2 of those 3.
Houston can only get 1 game of 3 from their top 2 starters, unless Verlander comes back Wednesday on 3 days rest.
Judgement calls aren't reviewable.
And IMO there was no obstruction in any case.
If Lewis was a little more canny, he moves left, into the catcher, and he might get the call.
But as it played out, he wasn't obstructed.
