Fantasy Baseball Waiver Wire Pickups: Pitchers to Add (Week 6)
This week’s group features a mix of streaming starters, ratio stabilizers, and speculative save plays. None of these pitchers are guaranteed league winners, but each has a path to fantasy relevance in the short term and potentially beyond. Here are four fantasy baseball waiver wire pitchers worth targeting right now.
Keider Montero (SP, RP – DET)
Detroit continues searching for rotation stability, and Keider Montero has quietly provided exactly that. He may not light up radar guns or generate elite strikeout totals, but fantasy managers in deeper leagues should not overlook what he’s doing.
Through six appearances, Montero has posted a 3.48 ERA with a 1.04 WHIP while maintaining a strong strikeout-to-walk profile. The strikeout upside is modest, but limiting walks has helped him stay effective and work deeper into games.
That matters in today’s fantasy environment. Managers are desperate for innings, quality starts, and ratio support. Montero can help in all three categories if deployed carefully.
The SP/RP eligibility is another bonus. In leagues with flexible roster settings, Montero can slide into multiple lineup spots while serving as a useful bridge during injury stretches.
Detroit’s offense still creates some concerns for win potential, but Montero looks like a viable matchup-based streamer and depth starter for fantasy rosters needing stability more than upside.
Sean Burke (SP, RP – CWS)
The White Sox rotation was expected to be a disaster entering the season, but Sean Burke has become one of the more surprising developments in fantasy baseball.
Burke owns a 2.72 ERA and 1.01 WHIP across seven appearances and has now delivered three straight quality starts. Like Montero, he is not an elite strikeout pitcher, but the underlying profile is encouraging.
His low walk rate has been one of the biggest differences. Burke is forcing weak contact consistently while limiting barrels, which has helped him outperform expectations early in the year.
There is also some meaningful pitch mix development happening. Burke has leaned more heavily on his knuckle curve while incorporating a sinker into the arsenal. The result has been improved deception and softer contact overall.
Fantasy managers often chase strikeout upside on waivers, but innings volume and quality starts are becoming increasingly valuable. Burke fits that mold perfectly right now.
If he strings together another strong outing, his roster percentage is likely to jump quickly.
Kirby Yates (RP – LAA)
Fantasy managers hunting for saves should be paying close attention to Kirby Yates.
The Angels bullpen lacks a clear established closer, but Yates has the experience and track record managers tend to trust in late-inning situations. Even on a team that may not generate a massive number of save opportunities, there is fantasy value available here.
Yates is now healthy again and appears positioned to reclaim meaningful ninth-inning work. While age is a factor at 39 years old, relievers have shown repeatedly that late-career rebounds are possible.
Kenley Jansen and Aroldis Chapman both revived fantasy value well into their late 30s. Yates could follow a similar path if the health cooperates.
Fantasy players should also remember how dominant he was just two seasons ago with Texas, posting a 1.17 ERA and 0.83 WHIP. That level of production is difficult to ignore when evaluating waiver wire closers.
Saves remain one of the hardest categories to chase during the season. Any reliever with a legitimate path to ninth-inning opportunities deserves attention immediately before the market catches up.
Jack Perkins (SP, RP – ATH)
Jack Perkins may be the most intriguing speculative add of this group.
The Athletics bullpen continues operating with a committee approach, but Perkins is making a compelling case for more save opportunities. Since late April, he has already picked up multiple saves while flashing excellent swing-and-miss stuff.
His strikeout numbers stand out immediately. Perkins has produced an elite strikeout rate while keeping walks under control, and his underlying metrics support the breakout potential.
The arsenal changes are also noteworthy. Increased changeup usage has generated strong whiff rates, and hitters are consistently chasing pitches outside the zone.
That combination often leads to fantasy success for relievers, especially those pushing for larger bullpen roles.
There is still some volatility here because Oakland may continue mixing and matching in save situations. However, Perkins has the talent profile fantasy managers should gamble on before the role becomes fully established.
In competitive leagues, speculative saves are often won a week or two before everyone else notices.
