Here's what Harper had to say about it afterwards:
“I don’t think 40,000 people came to watch him ump tonight,” added Harper, after his fifth career ejection. “Plain and simple. Especially when we’re playing the Yankees. The Yankees are a good team, we’re a good team and we’re rolling. I don’t want to get tossed. There’s no reason for me to get tossed in that situation. I don’t think I did anything bad to get tossed. Maybe he just had a bad morning or he didn’t get his coffee.”
This is one of a few times I've been to a game where a player and a manager were ejected. And this seems rather suspect. I don't think the home plate umpire was calling strikes all that well. I saw the replay when I got home and it sure did look like a ball to me. But the expanded strike zone did, I think at least, helped the Nats win the game.
More on that and pictures to come.
