Francisco Alvarez is not making this easy on the Mets. 

Billy Eppler’s front office soon will have to decide how to clear a catching logjam that does not have a simple solution and becomes more difficult with seemingly each Alvarez at-bat. 

Gary Sanchez hit at Triple-A Syracuse and had a nice Mets debut Sunday.

Tomas Nido, whose defense the club values, is amid a rehab assignment, and Omar Narvaez, who can be signed through next year, is expected to begin his own rehab assignment this week. 

The easiest path, and the one the Mets chose when they sent Luis Guillorme to Triple-A Syracuse last week, would be to option Alvarez simply because he is the only candidate who can be optioned.

If the Mets decide they value longer-term depth within the system and do not want to lose an in-house catcher, they could send Alvarez back to Syracuse. 

But Alvarez has taken a bat to that easiest path.

The 21-year-old has begun to show glimpses of the promise that made him baseball’s best prospect.

Since May 6, Alvarez has been baseball’s best hitting catcher. 

Entering MLB action Monday, Alvarez’s 1.058 OPS in the span, in which he has played 12 games, was the best of any catcher with at least 25 plate appearances.

Alvarez has clubbed four home runs and three doubles while sporting a .391 on-base percentage since May 6. 

His bat has been loud, but the soft hits have gained the notice of manager Buck Showalter, too.

Alvarez sparked the eighth-inning rally in Sunday’s nightcap by sticking out his bat against Cleveland’s Shane Bieber and powering a single over the glove of second baseman Andres Gimenez. 

“That’s a strength base hit,” Showalter said of Alvarez, for whom Starling Marte pinch ran and came around to score the go-ahead run. “A lot of guys, that ball just kind of flares out to second base, [and the second baseman] goes out and gets it.” 

Alvarez came through the Mets’ system known for his bat, and after a slow start, that bat has shown signs of breaking through.

His glove had been less heralded but arguably more impressive since his call-up.

Entering play Monday, Alvarez was the seventh-rated catcher, according to Statcast, at framing strikes. 

He has to improve on cutting down on opposing teams’ steals, but he has appeared to work well with the staff, including Max Scherzer and Justin Verlander. 

“He’s doing well. We’re proud of him,” Showalter said Sunday, ahead of the Mets opening a series in Chicago on Tuesday against the Cubs. “Every once in a while you have to remind yourself: He’s a sponge. He’s a really good listener.” 

Alvarez has begun to run with the job, but several are trying to catch up. 

Sanchez, the former Yankees All-Star, debuted with the Mets this weekend and drove a single to left field and lifted a sacrifice fly in four plate appearances. 

Nido played three games with Class-A St. Lucie this weekend in which he went 2-for-11 with a home run.

Nido is a lifelong Met, drafted in 2012, and was a Gold Glove finalist last season.

The Mets bought out his remaining arbitration years and thus will be paying Nido through next season. Nido struggled mightily (.266 OPS) through 19 games this year before hitting the IL with dry eye syndrome, which the club believes played a role in his offensive drop-off. 

Narvaez was an All-Star with the Brewers two years ago and brought in on a contract that pays him $8 million this season with a $7 million player option for next season.

He strained his calf in early April and likely will begin a rehab assignment Thursday or Friday. 

The Mets are likely to string along Nido’s and Narvaez’s time in the minor leagues, which would give them more time to evaluate each option (and more time in case someone gets injured or suffers a setback). 

It is possible the Mets could try to carry three catchers, particularly if Alvarez’s bat dictates that he becomes a DH option, but that would lead to a shake-up on an already-thin bench.

Daniel Vogelbach has been the usual DH option and is not an option in the field. 

It would be tough to keep Alvarez around.

But he is making it even tougher to send him back to the minors. 

“He’s been a tough kid, and I love the way he’s absorbing everything,” Showalter said. “The effort and energy has been contagious.”
