It's really surpring to me that he's only the 30th best pitcher in terms of fWAR in that stretch, at 1.1. Quintana is 13th at 1.7. Verlander is the one that is most confusing. I get all the home runs, but look at these two lines. Darvish: 62 IP, 11.32 K/9, 0.44 BB/9, 1.89 HR/9, .246 BABIP, 44.2% GB%, 23.6% HR/FB, 3.19/3.85/2.89 1.1 fWAR Verlander: 64.1 IP, 13.4 K/93, 1.12 BB/9, 1.40 HR/9, .268 BABIP, 32.9% GB%, 14.9% HR/FB, 2.38/2.71/2.76, 2.3 fWAR Verlander is better, but over twice as good? It's 1000% the dongs. fWAR is basically FIP times batters faced times some constant. By xFIP, Yu's basically as good as ever right now, but by FIP he's still fairly middling because of the dongs. I generally am a big xFIP guy unless a guy has years of over/underperforming it, but Yu's doing weird enough stuff right now that I'm not super confident in that belief.
