Best case scenario:
Durbin hits .750+ the rest of his time with BOS and plays near GG defense at 3B.
Arias is called up and hits the ground running with plus defense at SS and a plus bat from day 1.
That still leaves 2B wide open- something it's been since Pedey was healthy over a decade ago.
Romy can and maybe should DH more than play 2B/1B.
Mayer looks like the best odds on being the next best 2Bman, going forward. He's pretty good on D, which is better than we've seen over the last decade plus, but .650 ain't cutting it, and his leash is shortening. Injuries are another major concern for him.
IKF is on the IL and sees his control end after this season.
Monasterio, Seigler, Sogard & Cheng are not solutions- neither is Capra, Romero or other farm hopefuls. Winnay may surprise, but other than Arias, we don't have much hope in AA and AAA in non 1B infield promise.
Godbout has a "early 2028" ETA on soxprospects.com, so maybe he can help in a couple years, but we've put off fixing 2B for way too long. Waiting for Arias or Godbout seems like punting the problem, once again. Soto & Ramos are 3+ years away.
