Of course the word “good” is subjective, but there are 150 SPers slotted into the 30 teams inMLB, at any given moment in the season.
There are higher categories than “good” to most people.
Of course, anyone ca. set up their categories as they wish, but I would think one would be in a small minority, to think someone in the top 12-15 out of 150+ SPers is not in the “good” category.
Even factoring wins and losses as a very important stat for a pitcher. I can’t see not thinking Monty is not a top 30 pitcher, at the very worst. If not being better than 4 out of 5 or more other pitchers us not “good,” then someone’s standards are set very highly.
