Emerging Stars and Seasoned Upside: Key Sleeper Pitchers
Eury Perez: A Young Phenomenon Ready to Explode
Eury Perez stands out as an electrifying sleeper on many fantasy radars. His merchandise-quality value emerges from his excellent strikeout potential and strong underlying metrics reminiscent of elite arms. Notably, after a long-awaited return marked by immediate two-start opportunities, Perez has reignited excitement around his 2023 breakout performances as a 20-year-old phenom. His ability to accumulate strikeouts and maintain control positions him well in points-based leagues and head-to-head formats alike. However, fantasy managers should monitor health cues, considering past elbow concerns, as his availability could be a key factor.
Jack Leiter: Poised for Consistency and Upside
Jack Leiter, a top pitching prospect for the Texas Rangers, has shown a solid command of his repertoire through 41 innings pitched in 2025. Despite modest ownership percentages (around 20.5%), his strikeout upside and refinement in the majors make him a staple sleeper in waiver-wire discussions. Particularly attractive in leagues that reward strikeouts and quality starts, Leiter’s emergence complements strategies targeting two-start pitchers maximizing weekly opportunities.
Chris Paddack: Two-Start Gem with Streaming Value
Though not an underdog in the traditional sense, Chris Paddack’s two-start slate in Week 12 makes him an alluring pickup for managers looking to take advantage of favorable matchups. Streaming pitchers with multiple starts in a week often provide quantifiable upside, and Paddack’s solid but underappreciated skill set lends itself well to this role.
Cade Horton, Zebby Matthews & Landen Roupp: Deep Sleeper Options
Names like Cade Horton (Chicago Cubs), Zebby Matthews (Minnesota Twins), and Landen Roupp (San Francisco Giants) have surfaced in week-by-week waiver wire pickups, suggesting promising backend rotation candidates with upside. While they may not be top-tier aces, their inclusion in streaming and mixed league drafts can bolster pitching depth without costing high draft capital.

Strategic Considerations for Fantasy Managers
Emphasis on Two-Start Pitchers
A recurring theme in the Week 10 through 12 analyses is the advantage leveraged by targeting pitchers with multiple starts in a week. This approach maximizes counting stats—such as strikeouts and wins—and provides margin for error. Pitchers like Eury Perez and Chris Paddack exemplify this strategy, offering managers a tactical edge, especially in points leagues or head-to-head matchups.
Health and Workload Monitoring
With several young arms on the sleeper list, close attention to workload and injury status remains paramount. Eury Perez’s elbow history and interrupted playing time serve as reminders that upside must be balanced with durability considerations to avoid mid-season setbacks.
Leveraging Matchup Analysis
Targeting pitchers facing weaker offensive teams or clubs with higher strikeout rates can enhance the odds of strong outings. Sleepers often shine brightest when managers exploit favorable schedules, as highlighted by insights suggesting quality matchups against teams like the Tigers, Mets, and Twins as prime opportunities.

Impact of League Settings on Sleeper Value
League structure—such as 10-team vs. 12-team formats and scoring type (points vs. categories)—can influence the desirability of certain pitching sleepers. For instance, the article notes that in 12-team leagues, upside in the back-half of rankings holds more weight, increasing the relative value of emerging arms with high strikeout ceilings but less consistency. Conversely, points leagues might favor pitchers with strikeout prowess and the opportunity for multiple starts, reinforcing the profiles of Pérez and Leiter.

The 2025 fantasy baseball landscape reveals a rich vein of pitching talent hidden just beneath the surface. Identifying and capitalizing on pitchers like Eury Perez, Jack Leiter, and Chris Paddack—who combine strikeout ability, multi-start schedules, and favorable matchups—can differentiate astute managers in competitive leagues. Balancing risk through careful health monitoring and matchup evaluation while exploiting league-specific nuances enhances the potential to transform sleepers into cornerstone contributors. In the pursuit of fantasy glory, these underrated arms offer the gateway to sustained pitching success.
