To me it isn’t fair to the runner when the fielder without the ball is directly in the baseline. Hays is running full speed rounding 2nd and he then has to go around the 3rd basemen running full speed.
This was not a situation where with a direct path to the base he overslid the bag. I think obstruction could have been called.
I would actually like to see a breakdown of this play by MLB Network. If the throw is directly online it is late and he is safe easily unless of course he overslids. Problem is Hays never had that chance. A tag play was not possible, the throw was way late. Not like it was a bang-bang play.
