After last night’s game, Mickey Callaway indicated the team was looking to get only five innings out of Jason Vargas. This was the plan even with Edwin Diaz and Jeurys Familia being unavailable and with Seth Lugo feeling sick. With the Marlins hitting rockets off Vargas, Callaway held hard and fast to the plan removing Vargas after just 74 pitches.

While the win was nice, Vargas’ performance and the plan for him is troubling. After all, if the Mets cannot trust Vargas to go more than five innings against the Marlins, what are they going to do when he faces the other teams in the division? Do the Mets see him even reaching the fifth against lineups featuring Ronald Acuna, Jr. and Freddie Freeman, Bryce Harper and Rhys Hoskins, or Anthony Rendon and Juan Soto?

The answer is probably no, and the question is how the Mets plan to adapt.

The obvious choice is to remove Vargas from the rotation. The issue there is their Triple-A starters did not fare well in the Majors last year. While you may believe in Corey Oswalt‘s increased Spring velocity or Chris Flexen‘s new physique, it would be wise to give them time in Syracuse first to see if their offseason progress translates to results.

Since dipping into Triple-A isn’t the answer yet, nor is rushing David Peterson or Anthony Kay, the Mets most likely and perhaps most successful option would be to utilize an opener.

Last year, the Rays were the first to utilize an opener. In tabbing Sergio Romo as his opener, Rays manager Kevin Cash said, “The way that their lineup stacks generally speaking is very heavy right-handed at the top It allows us in theory to let Sergio to come in there and play the matchup game in the first . . . .” (Marc Topkin, Tampa Bay Times).

In essence, the goal of the opener is to get a traditional reliever to start the game and face a platoon advantage in the first. After the reliever gets through the top of the order, the starter can come in and “start” his game against the bottom of the lineup thereby permitting him to not only get an easier start to the game, but arguably, to get deeper into the game.

In the case of Vargas, you saw the Marlins stack right-handed batters against him. After all, it makes sense with right-handed hitters hitting Vargas well. Since the beginning of the 2017 season, right-handed batters are hitting .262/.324/.464 off of him, which translates to a 4.74 FIP.

As a result, the Mets need an opener who can counteract a team loading up their right-handed batters against Vargas. Given his history as a starter, it would make sense for the Mets to make Robert Gsellman as the opener on the games Vargas starts.

From what we see so far this season, Gsellman is not part of the late inning mix. That is reserved for Diaz, Familia, Lugo, and Justin Wilson. Rather, Gsellman is going to be used like he has been so far in this series. When the starter goes five (or less), he is going to be the first guy out of the pen to eat some innings before handing it to the late inning relievers.

If the team is going to use Gsellman for an inning or two whenever Vargas starts, why not make it at the beginning of a game? Why not put pressure on the opposing manager to opt for either having right-handed batters face Gsellman so they’re in place to face Vargas later, or to start their left-handed batters and have a wave of substitutions to face Vargas?

The point is by starting the game with Gsellman, Callaway would be creating a situation that is beneficial for Vargas to enter the game. If you are only getting five innings from him, why not make it against a team’s worse hitters? Why not use Gsellman against a right-handed lineup without fear of seeing a pinch-hitter? If nothing else, it can’t hurt.
