Three clubs are re-evaluating their rotations in the wake of top pitchers requiring Tommy John surgery.

New York Mets right-hander Noah Syndergaard, Boston Red Sox ace Chris Sale, and New York Yankees fireballer Luis Severino are out until some point in 2021, and while they'll be recovering from the same procedure, each team's impacted in different ways going forward. Let's break it down:

Boston Red Sox

What it means in 2020: They're probably cooked. This was always going to be a bizarre season in Boston after the Mookie Betts trade, and Sale's absence will only make things worse. Even if Eduardo Rodriguez can build on what he did last year, a rotation headlined by him, Nathan Eovaldi (who owns a troublesome elbow himself), and Martin Perez is not that of a contender. Dumping David Price's salary in the Betts trade looks worse now.

What it means long term: Worst-case scenario is a new rebuild, but one centered around a core of Rafael Devers, Xander Bogaerts, Michael Chavis, Alex Verdugo, and some yet-to-debut prospects. While that's promising, Boston's system is shallow when it comes to high-end, MLB-ready pitchers.
