Four Yankee Batters Ready to Regress
In looking through the largest discrepancies between in game production and my various xStats, namely xOBA, I noticed that four of the largest differences come from the Yankees. Disturbingly, these are in the negative direction, meaning xStats are making a claim that these four Yankees are playing over their head and are due for a regression. Who are these Yankees? Didi Gregorius, Carlos Beltran, Jacoby Ellsbury, and Brett Gardner.
Three left handed hitters and a switch hitter playing in Yankee stadium, a ballpark geared for left handed production. On first blush, you might scoff and claim the stats aren’t accounting for the ballpark, these guys are probably benefiting from the short porch. Yes, they likely are benefiting to some degree from the short right field fence, but last season didn’t seem to have this problem with the xStats from these four batters.
