Daniel Espino’s path back to the major leagues has been anything but conventional, and now his name is getting real recognition on a national level as a potential difference-maker come October. MLB.com highlighted him this week among a group of under-the-radar relievers who could end up having an outsized impact in the postseason.
The write-up on Espino focused on exactly why his recent stretch carries so much promise.
“Finally healthy enough to contribute, Espino made his long-awaited MLB debut this June, and while he’s been up-and-down since, he also has a 40% strikeout rate – in, admittedly, just a dozen innings – while averaging 98.8 mph on the fastball. He’s pitched five times in September, striking out nine without a single walk, and while there’s no doubt the samples are small, the issue here has always been health, not stuff,” Petriello wrote.
He first entered Cleveland’s system back in 2019 as a highly regarded arm, but the years that followed brought one setback after another. Shoulder injuries wiped out his 2023 and 2024 seasons entirely, and he managed to throw only a fraction of an inning at the Triple-A level in 2025. Across seven seasons in the organization, he totaled barely more than 130 innings, a staggering gap for a pitcher once considered one of the more exciting arms in the minor leagues.
This June finally brought the payoff those years of patience were building toward, as Espino made his long-awaited major league debut. The results since have been up and down in terms of consistency, which comes with the territory for any young reliever, but the underlying stuff has never been in question. He is averaging just under 99 miles per hour on his fastball and has struck out roughly 40 percent of the hitters he has faced across his limited innings so far. His September has been especially sharp, with nine strikeouts and no walks across five appearances during the stretch run.
The numbers behind his fastball specifically stand out even more. Among pitchers who have generated at least 70 swings against their four-seamer this season, Espino ranks second in swing-and-miss rate, trailing only one other reliever and sitting ahead of several of the most dominant closers in the sport. That kind of strikeout ability on a single pitch is difficult to fake, even across a smaller sample of innings, and it explains why evaluators are already circling his name as a potential postseason weapon.
Espino has already shown the versatility to work as a starter or in a traditional relief role, giving Stephen Vogt another trusted option as Cleveland tries to hold its spot atop the American League Central.
