Can Jacob deGrom actually top Bob Gibson's 1.12 ERA?

Through seven starts, New York Mets ace Jacob deGrom has a miniscule 0.80 ERA. To simply say it's the best in MLB so far this season doesn't quite do it justice.

No qualifying starting pitcher in modern history has posted an ERA under 1.00 for a full season. Yes, we've only reached Memorial Day weekend, but not only is this the Year of the Pitcher, deGrom is a legit challenger -- a two-time Cy Young winner and arguably the best pitcher in the game. If he can stay healthy -- which, to be fair, has been an issue for him in 2021 -- who says he can't break Bob Gibson's record 1.12 ERA set more than 50 years ago?
