The Grossman tag was a horrible baserunning decision. He was already in scoring position, in a tie game, and the fly ball was out two. Grossman runs like a man dragging a plow. There is some advantage to being on third with 2 out vs on second, but not much. If the throw was on line, he's out by 3 steps. In contrast, Rosario's gamble didn't just gain a base, it paid off in a run, with 2 out, and Adrianza due up. I don't think the throw gets him even if it's on line.
