Conclusion

Rosario is clearly the worst fielding shortstop of this group of five players. He is currently the worst fielding shortstop in MLB according to UZR/150 from Fangraphs for players with at least 600 defensive innings at the position. He is also probably the second-best offensive player right now behind Marte and ahead of Desmond.

His age gives him an advantage in learning a new position and makes it more worthwhile because he could have several years in CF before the physical skills decline and he has to move to an IF or OF corner or 2B.

His best category in degree of difficulty is Remote which actually makes sense since his basic physical skills are excellent even though he frequently struggles to access those skills on a routine basis. That skill set bodes well as a CF which involves purer physical abilities and less instinct than shortstop.

My suggestion is for the Mets to start easing him into CF now since the chances of making the postseason are between Remote and Impossible.

If his defense turns out average or better in CF and his offense continues to improve as it has this season, I see him as the regular CF next season. If his defense is okay but his bat regresses he’s a fourth outfielder (oh, we have so many of those). If his defense is below average in CF he becomes a bench player and will have to learn some more positions to earn playing time.
