The Twins have invested two years in turning Eddie Rosario into a second baseman.
Now it appears that effort may not have been necessary.
Even as the 21-year old Puerto Rican sharpened his defensive skills at the keystone in the middle levels of the Twins farm system, Brian Dozier was emerging as a Gold Glove candidate. Even as Rosario continued to impress scouts with his ability to hit line drives — the so-called hit tool — Dozier, 26, transformed into power threat in the major leagues.
So the Twins have what appears to be a surplus at second base. Dozier, of course, is already in the majors; Rosario finished the season at Double A and isn’t far from being major-league ready.
Which means decision time is approaching.
The two are, or project to be, different players. Rosario, converted from the outfield, may never be as good with the glove at second as Dozier. Dozier is unlikely to hit for average; there is some thought that Rosario will not continue his power production as he climbs the ladder.
Assuming that Dozier’s power production (51 extra base hits this year, 26 since the All-Star break) is real and not a small-sample mirage, he fits in the bottom half of a contender’s lineup. (It speaks to the problems of the Twins lineup that he’s spent most of this season hitting first or third.) Rosario has a higher ceiling as a hitter but also a lower floor.
I see three options here for the Twins front office:
■ Trade one;
■ Return Rosario to the outfield;
■ Return Dozier to shortstop.
I rule out the third immediately. Dozier established in 2012 that he simply doesn’t have the arm for shortstop. That caused him to play too shallow; that, in turn, reduced his range. Dozier is either a second baseman, or he can’t play.
