As we approach the end of May, the Major League Baseball season has reached a critical juncture for fantasy managers. The initial excitement of April has faded, replaced by the cold, hard data of two months' worth of performance. Perhaps no position is more volatile right now than the bullpen. In our latest Fantasy Baseball Stock Watch, we take a deep dive into the shifting landscape of closers and high-leverage arms, identifying who is seizing the ninth inning and who is losing their grip on the role.
The Meteoric Rise of Gregory Soto
If you have been scouring the waiver wire for saves, look no further than Gregory Soto. The hard-throwing left-hander has seen his fantasy value skyrocket over the last two weeks. Soto has transitioned from a situational setup man into a primary late-inning weapon, showing the kind of high-velocity stuff that can dominate a lineup. His ability to miss bats has never been in question, but his improved control in 2026 has been the catalyst for his ascent.
For managers participating in this week's Fantasy Baseball Stock Watch, Soto represents the ideal pickup. His strikeout rate remains elite, and more importantly, he has earned the trust of his coaching staff in high-leverage situations. If he is still available in your league, he is a priority add, as the window to acquire a legitimate source of saves is closing fast.
Louis Varland: Finding His Rhythm
While the focus is often on the ninth inning, Louis Varland is making waves as a versatile arm whose stock is trending upward. Varland has shown significant improvement in his secondary pitches, allowing him to navigate through opposing lineups with much higher efficiency. Whether used as a bridge to the closer or in a swingman role, his ability to provide solid ratios and strikeouts makes him a valuable asset in deeper formats.
Varland’s recent outings suggest a pitcher who has finally found his rhythm. His command of the strike zone has limited free passes, a crucial metric for fantasy owners looking for stability. As he continues to refine his approach, expect Varland to become a more permanent fixture in fantasy rotations and high-end relief discussions.
Kenley Jansen: A Legend in Decline?
On the opposite end of the spectrum, veteran Kenley Jansen is seeing his stock tumble. One of the most prolific closers in MLB history, Jansen has struggled with consistency throughout the month of May. A noticeable dip in velocity and a struggle to finish off hitters have led to several blown saves and elevated ERA marks. For fantasy managers, the concern isn't just the performance—it's the potential loss of the closer role entirely.
While Jansen’s experience is invaluable, the results on the field are becoming harder to ignore. In the context of a Fantasy Baseball Stock Watch, Jansen is currently a "sell" or at least a player to bench until he shows signs of a rebound. If you are a Jansen owner, now is the time to start looking at insurance policies within his own bullpen.
Emerging Arms: Yates, Taylor, and O’Brien
Beyond the big names, several other pitchers are demanding attention as the season progresses:
- Kirby Yates: Yates continues to defy age, proving that his splitter is still one of the most devastating pitches in the game. He remains a steady source of saves for those who gambled on him during draft season.
- Grant Taylor: A name to watch for the future, Taylor is beginning to show the flashes of brilliance that scouts raved about. He is a high-upside stash in dynasty and keeper leagues.
- Riley O’Brien: O'Brien has emerged as a dark horse in the bullpen. With a high-90s fastball and a sharp breaking ball, he is one injury away from a significant role change that could make him a fantasy star.
Final Strategy for Late May
The key to winning the saves category in fantasy baseball is staying one step ahead of the news cycle. By monitoring the Fantasy Baseball Stock Watch, you can identify the next Gregory Soto before they become a household name. As Kenley Jansen’s struggles continue, the door opens for others to step up. Keep a close eye on bullpen usage patterns over the next week, as the moves made now often define the standings heading into the All-Star break.
