Fantasy Baseball Week 12: Top Waiver Wire Sleepers to Target

As fantasy baseball managers navigate the mid-season grind, identifying high-upside waiver wire additions is critical for maintaining a competitive edge. For Week 12 (June 8-14), analysts have highlighted several sleeper hitters rostered in under 80% of leagues who are poised for production based on favorable scheduling and underlying performance metrics.

Key targets include San Francisco’s Bryce Eldridge and Seattle’s Colt Emerson. Eldridge is showing significant promise with elite exit velocities and strong expected batting average (xBA) metrics, while Emerson benefits from a high-volume schedule, as the Mariners are one of the few teams slated for seven games this week. Other notable mentions include Isaac Paredes, who appears to be finding his rhythm in Houston, and Mets rookie A.J. Ewing, who is positioned to capitalize on a week dominated by right-handed opposing pitchers.

These selections are particularly valuable for managers dealing with injuries or those seeking to capitalize on specific pitching matchups. By prioritizing players with strong Statcast data—such as Nate Lowe’s impressive expected slugging percentage or Jung Hoo Lee’s elite contact ability—fantasy owners can optimize their lineups for the upcoming scoring period. Monitoring these trends allows managers to secure productive assets before they become widely rostered, providing a strategic advantage in head-to-head and rotisserie formats.
