As the fantasy baseball landscape shifts in Week 15 of 2025, four starting pitchers have emerged as potential assets for savvy managers: Lucas Giolito, Trevor Rogers, Mitch Keller, and Emmet Sheehan. Giolito of the Boston Red Sox has found his stride post-injury, boasting a remarkable 0.83 ERA over his last five starts, making him a solid add for any fantasy team. Rogers, now with the Baltimore Orioles, showcases a 1.57 ERA in his recent outings, indicating he could be a matchup-dependent streamer. Mitch Keller of the Pittsburgh Pirates is garnering trade interest, and his current form with a 2.45 ERA over the last month bodes well for his value. Finally, Emmet Sheehan of the Los Angeles Dodgers has shown promise with two strong starts, but his long-term role remains uncertain due to a crowded rotation. Managers should consider these pitchers carefully as they weigh their waiver wire decisions.
