Some days he can, some days he can't -- it's why the Red Sox are likely to continue to their win-some-lose-some inconsistency (... or is that consistency?).
Cynics may view the Kike-at-shortstop experiment as a ploy by Boston to basically just field a team and sell pretension of contention to the fanbase, but what's also concerning is the lack of any authentic fulltime shortstop in the system's next level at Triple A.
The Bloom Era has always overemphasized versatility -- Marwin Gonzo was the Opening Day leftfielder in 2021 -- but shortstop is such a key position in stabilizing team defense. Instead, the starting shortstop in Worcester is David Hamilton, who the Sox won't call up, with multi-position guys like Fitzgerald, Koss, Meidroth and McDonough behind him or in Portland.
No one is saying Marcelo Mayer should be promoted to Fenway this year, but there may not be anyone else the system down to Luis Ravelo in Single A projected as an actual shortstop. Remember, the Reds' Matt McLain made the bigs before high schoolers drafted ahead of him like Mayer and Jordan Lawlar because he's 23 and played D1.
In the meantime, sit back and avert your eyes...
