I was just thinking anecdotally earlier that it seems like Nola doesn't pitch well against the Nationals. So, I went to baseball reference and sure enough, lifetime against the Nationals he's 6-6 3.86 ERA, clearly a comedown from his performance against the rest of the division.
Oh, and Trea Turner is a freakin' Phillie killer. .279/.335/.489/.824, 13 HR (more than against anyone else). As Harry would say, "He's really worn down the Phillies throughout his career."
