Much of the Houston Astros roster, especially the position player cohort, feels like a defective puzzle. There are several duplicate pieces, yet critical elements are also missing.
The most heavily discussed issue the Astros have is the logjam at the infield corners. There are only so many at-bats to go around for the trio of Carlos Correa, Isaac Paredes, and Christian Walker, and the bloated salaries of Correa and Walker almost ensure that they'll be in the lineup every day, despite Paredes being the only one of the trio who isn't on the decline.
Houston has tried to alleviate this by dangling Walker on the trade market, but so far, the response they've received has been crickets.
