For the first time since the New York Yankees decided Anthony Volpe was their Opening Day shortstop in 2023, there's somebody else ahead of him on the depth chart . It has been a long time coming for the player entering his fourth year, who regressed on defense a year earlier and has a career 85 wRC+ in 1,886 plate appearances. This isn't to say that José Caballero is the perfect option at shortstop, either. Caballero has been a spark plug this season on every side of the ball , with his baserunning, defense, and bat about league average since being traded to the Yankees last year. Even still, his underlying metrics are those of a player who probably won't be hitting like this all year. He has a .267 xwOBA, .221 xBA, .323 xSLG, 83.6 mph average exit velocity, a 3.5% barrel rate, and 29.4% hard hit rate. All of that equates to a sea of blue on his Baseball Savant page, but the results are the results, and it was the right move to name Caballero the shortstop. What does optioning Volpe mean?…
