In 2005, the first season in the bigs for Felix Hernandez, 50 major league pitchers threw at least 200 innings. He went on to have eight seasons of 200-plus.
By 2010, there were 45 pitchers who reached the benchmark. In 2015, 28. In 2016 and in 2017, there were 15 each season. In 2018, there will probably be fewer. None of them will be Mariners.
