Fantasy Baseball Waiver Wire: Roki Sasaki Emerges as Must-Add Pitcher

The Week 11 fantasy baseball landscape is highlighted by the breakout of Los Angeles Dodgers pitcher Roki Sasaki. After a rocky transition to MLB, Sasaki has refined his arsenal, notably replacing his sweeper with a harder slider and diversifying his forkball into two distinct pitches. Most impressively, his four-seam fastball has seen a significant jump in velocity and movement, culminating in a dominant performance against the Phillies. With a 3.18 ERA and strong strikeout-to-walk ratios in May, Sasaki has transformed from a speculative project into a must-roster asset in nearly all fantasy formats.

Beyond the pitching mound, fantasy managers should look toward offensive players experiencing shifts in playing time or performance metrics. Washington Nationals catcher Keibert Ruiz is a top target for those seeking a hot hand, as his recent surge in exit velocity suggests his production is supported by improved contact quality. For managers in deeper leagues, Mets catcher Francisco Alvarez is an intriguing stash candidate; despite his recent injury, his underlying metrics—specifically a reduced strikeout rate and high expected wOBA—indicate significant untapped potential once he returns from his rehab assignment.

Finally, the infield market offers value in Nationals utility player Curtis Mead. Following a roster shakeup in Washington, Mead is seeing increased opportunities against right-handed pitching. His career-best performance metrics against righties, combined with a strong May, suggest he is no longer just a platoon player but a viable starter for fantasy rosters. These additions reflect a broader trend of identifying players whose recent statistical improvements are backed by tangible adjustments in pitch selection or plate approach, providing managers with high-upside options as the season progresses.
