It's very hard to put total trust in Monasterio, and to a lesser extent Siegler- only because Monasterio is the only real SS on the 26. Okay, Sogard can play SS, but in no way does any of us feel Sogard will lead us to a ring.
Middle infield has been such a major nightmare for a very long time. We've seen so many players come and go, and several had some decent but all-to-short stretches, before falling off the radar. I'm not convinced that either or both are the answers to those problems, but man, they have looked real good for a couple weeks, anyway.
From 2018 to 2026, we've had 42 players play 2B. Here are but a few with innings:
1248 Arroyo, 914 Holt, 832 Nunez, 825 EValdez, 813 Story, 679 DHam, 584 Kike, 556 Chavis, 471 KC &418 Romy. Nobody else had more than 300 innings! The fact that Valdez places 4th and KC places 9th on this list pretty much says it all.
SS is a bit better, as Bogey held down the fort for many years- not great on D but very good overall. 5408 Bogey, 1913 Story, 692 Rafaela, 592 DHam, 566 Kike with nobody else over 300 innings. (Chang, Reyes, Holt and Lin over 175)
