On March 4th, Amed Rosario was hit on the kneecap with a pitch. He’s undergone an MRI, and it came back negative. While that is great news, it is important to note Rosario has not played since that March 4th game. More to the point, he is no longer being listed on the group of players available to participate in Spring Training games. When he will be able to return to the Mets is anyone’s guess right now.

The Mets are easing Rosario back, but given how this is the Mets, Rosario’s status for Opening Day is still in doubt. As such, it is time the Mets begin looking at alternative options.

To some, the answer should obviously be Jose Reyes. Reyes was signed to be the team’s top utility player, and as an extension of those duties, Reyes is the most obvious candidate to step-in and play any infield position for long stretches of time should any of the regulars get injured.

While the obvious choice, Reyes may not necessarily be the correct choice.

Defensively, Reyes’ -27 DRS made him the worst infielder in Major League Baseball last year. At his natural position of shortstop, Reyes had a -15 DRS in 630.1 innings played there last season. Believe it or not, the last time Reyes had a positive DRS season at shortstop was in 2007.

Given his experience at the position, the Mets would be more than jusified putting Reyes at shortstop for the occasional game. However, asking him to play there for extended periods of time would be to significantly compromise the Mets defense. Worse yet, you are doing that at the most important defensive position.

With the Mets signing Todd Frazier to play third, the left side of the infield defense has become one of the strengths for this Mets team. It would certainly behoove the team to keep it that way even in Rosario’s absence. That is why the Mets should really consider Luis Guillorme to take over for Rosario should he not be able to play on Opening Day.

In the absence of Rosario, Guillorme is the best defensive shortstop in the Mets organization. In fact, there are some who would argue Guillorme is the better of the two. Playing Guillorme at short in Rosario’s absence would maintain a great left side of the infield defense.

The obvious caveat here is Guillorme’s bat. He’s never hit for power, and there are many who question if it will ever play at the Major League level. Truth be told, the Mets are going to have to find that out sooner or later, so why not now?

Looking at his minor league numbers, this is a player who has shown an ability to get on base, which could give the Mets some hope he could profile as Luis Castillo – the Marlins version, not the Mets version. With Guillorme working on driving the ball, and showing some positive results for those efforts this Spring, his ability to stick in the lineup becomes less of a doubt.

And if we are being honest, his bat should not be a deterrent; at least not now. Since 2015, Reyes has been a 91 OPS+ hitter, and in each of those seasons Reyes has gotten off to some dreadful starts. Since 2015, Reyes has hit .205/.263/.301 in the Month of April.

With that being the baseline April production, the Mets should really consider starting Guillorme on Opening Day should Rosario not be available. The offensive floor is low, and his defense right now has no ceiling.
