You could also make an excellent case for Pacheco as the top third baseman available in this draft as well. A high school shortstop similar to Kath, Pacheco will most likely move over to third base going forward where his athleticism arguably suits him better, along with his plus-arm giving him a chance to succeed.
Pacheco displays a strong swing that produces plenty of power from the left-side, and quality speed on the basepaths. A Texas A&M commit, Pacheco is a candidate to go in the first round of this years draft, and should be an above-average third baseman going forward, given he transitions to the position early-on in his career.

As with the previous two, you can make an excellent argument for Montgomery as the overall No. 1 third baseman in this draft. A phenomenal multi-sport athlete in high school, Montgomery has excelled on the baseball field, mainly due to his strong left-handed swing that allows him to hit for both contact and power.
The 19-year old high school shortstop has quality athleticism at 6’4, drawing comparisons to current Dodgers shortstop Corey Seager, and will most likely transition to third base as well. While he is an Indiana commit, Montgomery will most likely become a first round pick in this draft as one of the biggest upside third baseman from this draft class.
While it potentially makes sense for the Miami Marlins to wait for one of the names mentioned at the beginning in the middle rounds, there is no denying that there are five clear top options should they select a third baseman early-on.
