Is Brooks Raley an over-achiever or an under-achiever?
He made a comeback last year with the Astros during the weird 2020 season. He hadn’t pitched in MLB since 2014, with a stint in the Korean League during that time, and his career was distinctly mediocre before then. His career ERA is 5.63. including his last two with the Astros.
So his two seasons with the Astros, with ERAs of 4.95 and 4.73 respectively, represent a kind of over-achieving.
But wait!
If you look at advanced stats Raley has been an under-achiever his whole career, including his career with the Astros.
