Amed Rosario Third Base Move Is A Bad Plan

During his press conference yesterday, Mets manager Luis Rojas indicated Amed Rosario will work at third base, but he will not be working in the outfield. This plan is not something which helps Rosario or the Mets.

One of the reasons is Rosario’s bat. It doesn’t play at the position.

Mostly buttressed by a 100 wRC+ in 2019, Rosario has a career 89 wRC+. From 2016 – 2019, MLB third baseman had between a 102 – 105 wRC+. That puts a typical Rosario season well below the threshold.

To even justify Rosario at third, he’s have to play elite defense. His ability to do that is certainly up for debate.

Rosario’s defense has been gradually improving, but it appears like he’ll never reach the Gold Glove aspirations many had for him, nor will be surpass Andres Gimenez.

By OAA, he made huge strides in this shortened season going from a -8 OAA to a 2. DRS paints the same picture with his going from a -10 to a -3.

This past season, what stood out was he’s better able to go to his right. However, in a normal season, he was far better going to his left. Certainly, if he has the range for short, he should for third.

Looking at these numbers, Rosario can certainly play third. However, that’s not the issue. As noted, he needs to play at an elite level due to his bat.

Now, you could argue he’s a better option than J.D. Davis, which he certainly is. Davis is incapable of playing the position, and without the juiced ball, his offense came hurtling back to earth.

However, this shouldn’t be the test. Just being better than Davis isn’t sufficient. Again, the Mets need a real third baseman. Rosario has not shown yet he can be that with his offense being the biggest issue.

His offense won’t be as much of an issue in center. In three of the past four seasons, center fielders we’re below league average offensively. As noted, Rosario does have the tools to succeed in center.

If nothing else, Rosario should be working towards being a good center fielder. If he’s lost the shortstop job, he needs to become as versatile as possible. Learning center does that.

Overall, Rosario’s chances of success at third are not as good as his chances of success in center. Regardless, he needs to work on both as he’s now a bench player. That’s why focusing just on third is a very bad plan.
