His play may have been the dirtiest play of the year in MLB so far, but I was pushing the point. But fans love a villain and Brett Lawrie plays that role for KC fans.
You listened to different announcers than i did. Our color announcer, Rex Hudler started out saying it looked like a hard slide, but after the reviews he was clearly on the side of it being a dirty play. I even heard the A's announcers questioning it after watching the replay.
By the way, It's also part of baseball to plunk a batter after he injures a star player with a reckless, or intentional slide. It's baseball.
