It’s an age-old question when it comes to the Dodgers, cast upon a new-look roster battling familiar injury-related headaches.

In a best-case scenario, the Dodgers could end the season with Yoshinobu Yamamoto, Blake Snell, Tyler Glasnow, and Shohei Ohtani (in some capacity) headlining their rotation.

In the bullpen, they could have Blake Treinen, Michael Kopech and Brusdar Graterol bolstering more heavily-used arms like Tanner Scott, Alex Vesia and Kirby Yates — plus wild card options in Ben Casparius, Emmet Sheehan and Jack Dreyer to serve in more versatile roles on the mound.

But best-case pitching scenarios, of course, have often been unrealized fantasies with the franchise in recent years.

Thus, down the stretch this season, the Dodgers’ top priority (after winning the division and securing a first-round bye) will be keeping their arms as healthy as possible.

That will be most important with Glasnow (who just returned from a shoulder injury) and Snell (who should be back from his own shoulder problem in the next couple of weeks). To this point, the Dodgers have signaled a reluctance to urgently pursue a starter at the trade deadline. And even if they did, the lack of available front-line options means it’d be difficult to insure against either (or, in a nightmare world) both going down again.

The Dodgers have been interested in adding to the bullpen, and might set their sights on a legitimate closer given Scott’s season-long struggles. But still, much of their depth will depend on Treinen (who is also nearing a return from a forearm injury), Kopech (who went on the 60-day IL after a knee surgery, but is still expected back this season) and Graterol (who is also still expected to return after missing the first half recovering from offseason shoulder surgery).

The Dodgers also have their fingers crossed on Roki Sasaki (hoping he can return in late August from his own shoulder issue) and haven’t yet ruled out Tony Gonsolin (though he has remained shut down since suffering an elbow injury). But for now, their primary hope is to keep Glasnow and Snell upright, and replenish an overworked bullpen with late-season reinforcements.
