Unlike other sports, MLB teams typically go with the best available players and find a fit later. The Astros have been a prime example of this after drafting shortstop Alex Bregman in the 2015 draft. They had Carlos Correa already entrenched at shortstop, and on the night of the draft, George Springer told him that they drafted his replacement. Little did he know that Bregman would make his debut the next year as a third baseman.
After drafting Bregman, they drafted Kyle Tucker with the fifth overall pick of the draft.
