I took a look at the 120 Mets games played so far this year. (Relatively small sample size, but it's what I have available to me.) That's 240 starting pitchers. In 94 of those 240 starts, the starter pitched fewer than six inning and gave up fewer than four earned runs. So under that rule, most of those starters would have stayed in the game longer. (I assume some of them may have reached the 100 pitch count.) That's a higher number than I would have guessed. I looked at the numbers for previous seasons, where the denominator would be 162 * 2, or 324. In 1970, only 45 of the 364 starters pitched fewer than six innings while giving up fewer than four earned runs. In 1980, it was 69. It was 50 in 1990, 50 in 2000, 54 in 2010, and 161 in 2021. (I skipped over 2020 for the obvious reason.) 122 in 2022, and 117 in 2023.
