Earlier this week, I was marveling at Jacob deGrom’s last two seasons, and I noticed something. He’s on another level, one all his own, but take a look at these two mystery players over 2018 and 2019:
Player A has been worth a whopping 10.9 fWAR and 10.7 bWAR over the past two years. He was the 5th-best pitcher in baseball by fWAR last year and the 11th-best this year -- in other words, he’s great. That’s Patrick Corbin, the Diamondbacks and Nationals stud. Player B? That would be Jack Flaherty.
