The rotation probably mostly exists on paper. It’s easy (and to some degree, logical) on the forum to discount Sale and Paxton. But as they will (if/when Paxton’s option is picked up) combine for $40-ish mill in AAV. they won’t be ignored. With Pivetta likely back (although he could certainly be traded) and Bello making a strong push, the rotation could require a single pitcher at the MLB level. With Eovaldi likely getting a QO, and Wacha earning attention, the rotation for 2023 might already be in the organization.
Of course, depth beyond Mata, Ward, and Crawford will become essential…
