The Nationals are 17-9 and have the biggest RD at +45, which means their record is pretty much right on their pythag (16.4 wins). For comparison, last year the Cubs were 20-6 with a +93 RD at this point (pythag 21.6 wins). So even after 3 blowout wins in the past week, the Nats RD isn't even half what our was at the same point last year.
