Miami Marlins could be overthinking things with lineups versus lefties

The Miami Marlins have done a lot of smart things since Peter Bendix took over.

They have smartly overhauled the scouting department. They have smartly dramatically expanded their use of analytics. They have perhaps smartly revolutionized pitching, although the jury remains out on that one across the league, as an article in The Athletic recently covered. They have made a bevy of smart signings and smart trades. All welcome and needed changes for an organization that had been decidedly unsmart for far too long.

However, it is possible to overthink things at times, to occasionally be too smart- not that I have any personal experience with that last point. And thus far in 2026, the Miami Marlins are looking to be in danger of doing just that when it comes to their left-handed lineups.

Heading into play this past weekend against the Yankees, the Marlins had two of the Top 10 RBI leaders on their roster. As of Monday, C/1B Liam Hicks remained tied for first place on the RBI leaderboard. Yet both Hicks and Owen Caissie, a Top 50 MLB prospect, have found themselves repeatedly pulled from a lineup already missing their best power hitter in Kyle Stowers. Griffin Conine has also frequently found himself losing playing time in the name of avoiding the tragedy of a lefty on lefty matchup. Finally, Xavier Edwards might be the best hitter on the team, and continues to be relegated to the bottom of the order when a lefty takes the hill.

Now, part of the problem is the ridiculous amount of lefties the Marlins have faced in such a short span of time. Miami has now played ten games- six of those have been versus lefty starters. Tuesday night's game will make it seven overall and four straight: Ryan Weathers, Max Fried, Brandon Williamson, and Andrew Abbott. That's...not normal.

Then there's the fact that whatever sample size you pick here- four games, seven games, eleven games-remains unreliably small. Presumably the Marlins analytics team are taking far more into account than what has transpired in 2026 when making these lineup decisions. You don't need to have ever been guilty of being too smart to know that much.

Still, there has been a lot of taking the bats out of the hands of Miami's highest impact bats in the name of a platoon advantage. Too much, in all likelihood.

The argument starts with Caissie, who again came into the year as a Top 50 prospect. Those players generally don't get relegated to a platoon role before losing rookie status. While there is certainly something to be said for protecting young players and building their confidence early on, barring them from facing lefties to this extent sends a message that could be just as negative as picking up a Golden Sombrero against a tough lefty pitcher would. Plus, speaking of "tough" lefties, there has really only been one of those on the schedule. Max Fried you can see game planning around. Brandon Williamson et al? Not so much. Caissie should have started Monday night.

After Caissie, whose talent should just transcend the need for these kind of maneuvers, the issue becomes more about what the replacements are doing with these extra at-bats. Unfortunately for the Marlins, the answer has been next to nothing.

Austin Slater? Batting .133/.176/.133- just 2 for 12 to start the year, with two singles (off of a lefty to be fair).

Heriberto Hernandez? Batting .130/.226/.185- hardly inspiring.

What about Connor Norby, who has been taking some 1B reps away from Hicks this year? Glad you asked- he's hitting .148/.303/.222 so far.

Obviously, all those numbers are terrible. Surely though, they've done better against the lefties they've faced, right? And conversely, those other bats have a track record of really struggling against them?

Actually, that's gonna mostly be a no. Hate to break it to you, but Hernandez is .091 against them this year. Norby too has been worse against lefties in 2026. Slater has only faced lefties, so I can't call anything out here other than to reiterate he has not been getting the job done enough to warrant the playing time he's gotten.

On the other side of this, Hicks has been genuinely bad against lefties in his career and this season. The Marlins did show a willingness to let him try his luck against a lefty starter given how hot he has been, but I would quibble with the fact that the lefty they were willing to let him come out and try this against most recently was Fried. I'd have sooner seen Miami bench him Sunday in New York and have run him out there against the much more mortal Williamson Monday night at home. Having said that, he probably doesn't need to do too much starting versus left-handers.

But Caissie and Conine are different stories. Caissie has a .286 average versus lefties this season, and actually holds that number when you tack on his 2025 stats. Conine is a .304/.347/.457 career hitter against them. That line does include a .200/.200/.200 line in 2026, but even if you believe that do his norm versus lefties, that does sadly beat out the stats being put up by the players bumping him from the lineup.

As for Edwards? Entering play Monday he was baseball's leader in average and hits, and boasted a .455/.500/.545 line against lefties on the year. He can probably go ahead and keep that leadoff job no matter who is on the hill.

Ultimately, Caissie has been too good and has too high of a pedigree to be treated as anything but an everyday starter. Then in regards to everyone else, Miami's right-handed role players don't have the track record to prove they deserve this kind of favoritism. Yes, that could change, and yes, that will only change with reps.

Unfortunately, I'd have to argue that what has been done thus far has been an overcorrection, and Miami needs to change course. Quickly.

The Marlins need all the pop they can get, pure and simple. There's just no need to be this cute.
