X-man is hitting .275 and that will be his average at the end of the season. He will end up with @90RBI. Combine that with his fine defense and it will be a very good year for him.
I will concede that Lester did have to pitch in the AL for much of his career and Nola does pitch in the weaker NL. When Lester moved to the NL, his pitching stats were much improved.
JD can't resist those low outside pitches. But when the pitcher doesn't get it low or outside enough, JD makes them pay. Nola just has outstanding control.
