Ok, I watched it.
Easy to see in hindsight, but I don't mind that Grandy tagged up on the Morales drive. If that's caught, he's moves to 3rd with 1 out, representing the tying run. If the ball's gone, the game's over and if the ball hits off the wall and gets away from the OFer (which was a possibility if Trout tries to make a leaping catch), then he scores also. With nobody out - I don't fault him at all.
Morales should have been on 2nd after hitting the ball. That's bad and would have been awful if Teo hit into a double play.
It was the coaches fault for sending Grandy on Teo's fly ball to RF.
