NL Division Series Preview: Miami Marlins vs. Atlanta Braves
This preview isn’t a rehash of Miami’s remarkable regular season campaign. It’s about the five games that will be played to determine a spot in the NLCS. Both of these teams will come into the series rested and ready, at least to the extent that anyone is rested and ready at this point in the year. That doesn’t mean the regular season performance of both teams doesn’t matter, though, because it provides a window into both how these clubs are built and who is likely to win.
We’d be talking more about Acuna’s season if it weren’t for Freeman, who took his normal controlled aggression to a new level. He walked more often than he struck out for the first time in his career, batted a video-game-on-easy-mode .341/.462/.640, and had the underlying batted-ball metrics to back it up; a career-high barrel rate and hard hit rate were backed by a ludicrous 31.1% line drive rate. His 187 wRC+ was second only to Juan Soto‘s 200 mark across all of baseball.
Behind Freeman and Acuna, the Braves have yet more pop. Marcell Ozuna is having a bounce-back season after two years of middling numbers for the Cardinals. Ozzie Albies is more than just a favorable contract; he’s also a solid hitter with above-average defense. Travis d’Arnaud, a castoff only a a year ago, hit a BABIP-aided .321/.386/.533 this year. Maybe you can’t count on d’Arnaud to keep that up, but the rest of the lineup — Austin Riley, Adam Duvall, Dansby Swanson, and even Nick Markakis — provides admirable depth to go along with the headliners.
The job of stopping the dynamic Atlanta offense will fall to a precocious Marlins pitching staff. Sixto Sanchez would be my choice for NL Rookie of the Year if I had a vote; he made only seven starts, but he immediately looked like he belonged. His four-seam fastball averaged 99 mph, a remarkable number for a starter even in velocity-mad 2020. His changeup and sinker were excellent as well; they combined to prevent opposing hitters from putting anything in the air, a key part of his phenomenal 0.69 HR/9 rate.
After Sanchez, Sandy Alcantara and Pablo Lopez will both certainly make starts. Alcantara took a step forward this year after some inconsistent performances in 2018 and 2019. He set a career high in strikeout rate (excluding an 8.1 inning stint with the Cardinals in 2017), a career low in walk rate, a career high in groundball rate, and career lows in FIP, xFIP, and SIERA. Alcantara has always lived off of his fastball, and he’s throwing his sinker more than ever this year to good effect.
Lopez is a clear third in the hierarchy at the moment, but he too gets a ton of grounders while still missing bats — his 24.6% strikeout rate this year doesn’t look like a fluke, as he got more chases and missed more bats than any of his previous major league seasons. After Lopez, it gets dicey — Daniel Castano will probably make a start, and both Jose Urena and Trevor Rogers are acceptable fifth starters.
Those starters would be well served to go deep into games, because Miami’s bullpen was abysmal this year. They looked excellent in two games against the Cubs, but Brandon Kintzler, Brad Boxberger, and friends were terrible on the year as a whole, and Braves batters hit .315/.395/.589 against them in 10 meetings this year, good for an 8.69 ERA and 6.65 FIP. The less the Marlins have to rely on their ‘pen, the better.
On balance, Atlanta has the edge when they’re batting. Their powerful lineup doesn’t need to win against Miami’s rotation, merely fight them to a draw and get to the bullpen. Most of the time, the playoffs would allow a more focused bullpen, minus the chaff, which might make Miami’s weakness less glaring. In their case, however, the entire bullpen is made up of chaff — only Yimi Garcia pitched 15 or more innings with an above average xFIP or strikeout rate.
If the Marlins want to win, then, they’ll need to do it with generous contributions on the offensive side of the ball. This season, that production has come mainly from Miguel Rojas, Brian Anderson, and Garrett Cooper. Rojas, a glove-first shortstop who had never displayed much power before, cracked 10 doubles, a triple, and four homers in only 143 PA. Nothing in his batted ball data backs up the breakout, however, and even the Marlins don’t seem to believe it — he has batted seventh and eighth in their two playoff games.
Anderson, on the other hand, looks like the real deal. For a third straight season, he put up solid offensive numbers in relative obscurity. His only real shortcoming this year was a troubling uptick in swinging strike rate that ballooned his strikeout total, but he made up for it with more barrels and more power in general.
Cooper has flown under the radar in Miami, but he’s looked like a diamond in the rough this year; a bruising righty slugger who hits too many balls on the ground but makes up for it by spraying those grounders and making the most out of the balls he does hit in the air. He’s one of the rare hitters in baseball who doesn’t suffer against breaking balls; he does far more damage on contact against bendy stuff. That could pose a problem for any pitchers who like to spot in-zone breaking balls as a way to get ahead in the count.
Miami has some other hitters capable of hurting the Braves. Jesus Aguilar can still take mistakes out of the park and just posted the lowest strikeout rate of his career, albeit in only 216 PA. Matt Joyce still hits righties. Jon Berti provides league-average hitting and wow-he’s-fast speed. Corey Dickerson is a member of the Marlins.
One key question for Miami’s offense remains unanswered: what will become of Starling Marte? Marte was the team’s big deadline acquisition, likely the best offensive player on the team. He suffered a fractured pinkie when Dan Winkler hit him on the hand in Game 1 of the Wild Card series, and his availability is as of yet unknown. The Marlins played Magneuris Sierra in center field to replace Marte, a tough blow for an offense that was already short on difference-makers.
Atlanta has dealt with injury issues of their own; Mike Soroka and Cole Hamels, two of their top three starters, are both out for the year. Even pickled pepper picker Philip Pfeifer, a pitching prospect who was expected to be depth in case of injury, is out. That leaves Max Fried and Ian Anderson as the last two impact starters, with some combination of Kyle Wright, Huascar Ynoa, and maybe even Fried on three days’ rest to fill out the rest of the rotation.
The Braves didn’t allow a single run in their two games against the Reds, and while Fried and Anderson won’t get to pitch in every game of the NLDS, the bullpen will. Atlanta’s bullpen was excellent this year; Mark Melancon and Chris Martin led the way for a deep unit. Tyler Matzek, A.J. Minter, Shane Greene, and even Josh Tomlin all had excellent seasons. Will Smith was abysmal, but anyone can be abysmal in 16 innings — he struck out 29% of opposing batters but was victimized by a brutal 33.3% HR/FB; a full third of the fly balls he surrendered left the yard, and that probably won’t continue.
If the Braves are hoping to fight to a standstill against Marlins starters and then thrive against the bullpen, Miami needs to thread a trickier needle. They’ll be at a disadvantage against the high-octane parts of the Atlanta bullpen, and if Fried and Anderson are in late-season form, that’s no great shakes either. The latter part of the starting rotation is the best place to strike, but — curse you, math — it won’t come into play in the first two games of the series.
I’m not exactly going out on a limb here by saying that the Braves are heavily favored in this series. ZiPS sees Atlanta as 76.8% to win the series, about as lopsided as a five-game series can get. The Marlins have never lost a postseason series, as you might have heard once or 50 times during last week’s broadcasts, but they’ll need to pull off an upset against an opponent far more formidable than the Cubs to keep that streak going.
