Rubby De La Rosa is the Arizona Diamondbacks ace this season, and he continues to prove that every time he takes the mound.
4.32
In 25 starts this season across 156.1 IP, that is De La Rosa’s earned run average.
For most fans, that follow the game of baseball closely, that isn’t exactly ace material.
However, when you consider that the Arizona Diamondbacks rotation for the year has a 4.42 ERA as a staff, which is the fifth worst mark in baseball, then it makes sense that Rubby’s ERA is the lowest.
