Santana was originally was a catcher who the Indians acquired from the Los Angeles Dodgers for Casey Blake (who later became a Rockie) in 2008. The Indians gave him number 41 when he got to the major leagues because he was a switch hitting catcher from Latin America who had a very similar batting stance to his predecessor, who also shared these traits: Victor Martinez, who wore number 41 himself.
Santana made his MLB debut in 2010 as a catcher. Over time, the Indians transitioned him to first base. They also tried stints at third base (that was not a pretty sight) and, occasionally, have used him corner outfield spots (in a pinch). In the past three seasons or so, the Indians have used him as a designated hitter and first baseman. So, he is versatile on the field but he is also versatile in the lineup.
Just in 2017, he hit sixth in the order in 49 games, first in 37 games, fifth in 28, 4th in 26, seventh in nine games, and third in four games (he technically hit ninth too but that was only for a pinch hitting appearance). In 2016, he hit leadoff in 86 games and fifth in 59 games (with a few games in other positions sprinkled in). So, he can hit just about anywhere in the lineup for the Rockies. He’d primarily play first base if he were to become a Rockie but he can play the outfield in a pinch (but he hasn’t played third or caught since 2014).
But why has he in so many place in the lineup?
