With the fantasy baseball season now well underway into June, it becomes imperative for team managers to critically assess their rosters and make informed decisions about player retention. While typically focusing on acquiring new talent from the waiver wire, this piece shifts the spotlight to existing players, particularly those whose recent performance suggests they may no longer be viable assets. By analyzing key statistical indicators over the past six weeks, we aim to pinpoint hitters who are underperforming across crucial metrics, helping managers determine whether to release them, explore trade opportunities, or re-evaluate their potential.
The analysis specifically targets the period from May 1st to June 16th, deliberately excluding early-season statistics to focus on current form rather than initial hot streaks. A comprehensive leaderboard was constructed using four vital metrics: barrel rate, zone contact rate, chase rate, and heart swing rate. Players who consistently fell below the league average in these categories were identified as potential candidates for roster changes. The rationale is straightforward: hitters struggling with hard contact, failing to make sufficient contact within the strike zone, swinging too often at pitches outside the zone, or being overly passive on prime pitches are unlikely to contribute positively to a fantasy team's success.
While most players on this list exhibit significant deficiencies across multiple metrics, some were included even with only one notable weakness to facilitate a broader discussion. It's important to differentiate between players who should be outright dropped and those who might still hold value as trade bait. Additionally, certain players, despite analytical red flags, could still be worth keeping due to their contributions in specific categories, such as stolen bases. For instance, athletes like Randy Arozarena, Brayan Rocchio, and Fernando Tatis Jr. have maintained respectable wRC+ figures and high stolen base counts since May 1st, despite exhibiting some concerning underlying batting tendencies. Managers with a strong need for steals might retain these players, but should be wary of potential declines in other offensive areas, suggesting that trading them for better value could be a prudent move.
A deeper dive into individual cases reveals varied situations. Fernando Tatis Jr., for example, shows an average approach with league-average barrel, zone contact, and chase rates. His elevated batting average is supported by a high BABIP, indicating potential regression. Brayan Rocchio, while contributing stolen bases, displays a remarkably low barrel rate and a passive swing approach on optimal pitches, making him a candidate for dismissal if stolen bases are not a primary concern. Chandler Simpson and Nico Hoerner, known for their contact skills and speed, have not delivered expected stolen base production and are hitting well below .225, rendering them less valuable unless steals are desperately needed. Other players like Ezequiel Tovar, Xander Bogaerts, Brooks Lee, Willi Castro, and Carter Jensen are widely owned but may only be suitable for deeper leagues, with Jensen's struggles being particularly notable despite his potential. Vinnie Pasquantino's injury further complicates his value, making him a clear drop candidate.
Even highly-rostered stars like Trea Turner, Vladimir Guerrero Jr., and Gunnar Henderson warrant consideration for trade. Turner, at 33, shows signs of age-related decline in power and contact skills, though his speed remains an asset. Vladimir Guerrero Jr. continues to struggle with power, exhibiting career lows in barrel and hard-hit rates, along with a more aggressive approach outside the zone. Henderson, while providing power, shows an over-reliance on maximizing launch angle and pull rates, which could be unsustainable. These players are not necessarily cuts, but their underlying metrics suggest their current production may not be sustainable or could be acquired more efficiently through trades. Finally, Dansby Swanson, Alex Bregman, Steven Kwan, and George Springer are highlighted as players whose declining performance, whether due to approach issues, age, or personal challenges, makes them less desirable for most fantasy formats, with some, like Swanson, being outright liabilities.
