Back in 2022-2023, the pitching matchup in tonight’s Braves-Marlins series finale would’ve been heralded far and wide. Things are a little different these days, but that doesn’t mean that either team will have an easy path to a victory. The Braves can no longer lose this series after yesterday’s victory, but they can indeed still win it, and that’s what they’ll try to do as Spencer Strider faces off against Sandy Alcantara in Miami.
From 2021-2023, Alcantara was not just a workhorse, but a dominant hurler. He pitched 619 frames across 93 starts in that span, going from 4.3 fWAR in 2021 to 5.9 in 2022, before wearing down into something worse but still above-average in 2023 (3.0 fWAR). Part of that wearing down was his elbow ligament making a sad face late in 2023, as he missed most of September of that season, and all of 2024, with Tommy John Surgery and the associated recovery. Alcantara’s 2025 comeback campaign was a mixed bag at best — the righty had a career 78/90/94 line through 2023 (ERA-/FIP-/xFIP-), including a 73/82/85 line during the ‘21-’23 span mentioned. He stumbled around to a 126/103/101 line last year, giving the Marlins durability (31 starts) but less in the way of length (“just” 174 2/3 innings) or effectiveness.
In 2026, things are better for him in some ways, but not others. He’s once again pitching more deeply into games — 63 2/3 innings in ten starts — on the order of what he managed in 2021 and 2023 (but not 2022, where he averaged over seven frames per outing in his Cy Young-winning campaign). His ERA- and FIP- look better, both at 86… but his xFIP- is at 102. He’s running a career-low strikeout rate of just 16.9 percent at the moment, but riding high due to a teeny-tiny HR/FB.
He’s also been somewhat inconsistent in decently-long stretches. He had three nice outings to start 2026, including a complete game shutout of the White Sox, but then gave up four homers (the only four homers hit off him so far this year) in two starts, part of a bigger six-start stretch where he had a very blah 150/119/123 line. But, he then bounced back to dismantle the playing-very-good-ball Rays last Saturday, with a 6/0 K/BB ratio in what was arguably his best start since coming back from surgery, and perhaps his best start since winning the Cy Young Award back in 2022.
The Braves and Alcantara have a ton of history, as he’s made 16 starts against them in his career. His aggregate line includes a 3.99 FIP and 4.38 xFIP in 100 2/3 innings versus the Braves, which is notably worse than his performance overall. Even last year, facing a moribund team while perhaps still recovering himself, Alcantara’s performance wasn’t dominant: one good start, one okay start, and one where the Braves, diminished as they were, roughed him up.
On the flip side, the Braves will have Spencer Strider vying to suppress the Miami attack in the way that Chris Sale was able to on Wednesday. Strider’s three starts so far this season have also been a mixed bag: a struggle in his season debut at Coors Field, an evisceration of the Dodgers in Los Angeles, and then, most recently, a meh start against the Red Sox with a 4/3 K/BB ratio where he lasted 5 1/3 innings. On the season, Strider’s line is an appropriately-silly-for-three starts 60/90/101. I guess that makes this a pretty fitting matchup with Alcantara, as a battle of starters-that-are-currently-fortunate-to-have-a-low-HR/FB and who were once dominant, but are now working their way back to something more than mid-rotation candidates.
Strider has five career outings against the Marlins, though two were relief appearances in 2022. He completely obliterated them in two separate starts in 2023, and had a weirdly meh outing where he nonetheless went seven frames against them last season. There wasn’t much doubt about this, but Strider’s effectiveness in this one is going to be based on his own mechanics rather than any shared history.
