Fantasy Baseball Waiver Wire: Midseason Pickups to Boost Your Roster

Midseason insights on emerging stars and streaming pitchers

The Pitching Surge

Midway through the fantasy baseball season, the waiver wire has become a battleground for managers seeking that extra edge. While starters dominate the headlines, a handful of relievers and utility players are quietly reshaping matchups and roster percentages.

Among the most compelling arms is Clay Holmes of the New York Mets, who has posted a 2.39 ERA and a 1.10 WHIP across his first nine starts. His high‑strikeout profile and ability to lock down late‑inning leads make him a prime candidate for streaming in deep leagues.

On the hitting side, A.J. Ewing continues to blend contact with speed, sitting at a .267/.341/.415 slash line while already stealing 12 bases. The combination of on‑base skill and sprint speed gives him a rare upside for mixed formats.

Ty France, a mainstay for the San Diego Padres, is batting .286 with 16 home runs and a 142 wRC+ in 273 plate appearances, proving that consistent middle‑of‑the‑order production can still be undervalued in trade markets.

Dylan Beavers has surged since the break, slashing .321/.406/.393 and adding four stolen bases, signaling a potential breakout that could shift the balance for teams needing a left‑handed bat with speed.

Other names worth monitoring include Christian Encarnacion‑Strand, who has already cracked three home runs with a 216 wRC+ in just 30 plate appearances, and Cooper Pratt, whose .290/.362/.410 line and eight steals make him a versatile option at the bottom of the order.

The pitching depth extends beyond the Mets, with Keider Montero posting a 3.14 ERA and 1.06 WHIP over 22 games, while Zac Thornton has dazzled with a 1.93 ERA and 0.86 WHIP in his first three starts, offering a high‑risk, high‑reward streaming profile.

Payton Tolle, currently 24th on the list of most‑added players, embodies the archetype of a future ace, combining a low WHIP with a rising strikeout rate that could translate into weekly starter status.

In the outfield, Gabriel Moreno is hitting .315/.396/.458 with seven homers and four steals, while Luke Weaver’s 1.93 ERA and 0.83 WHIP underscore his reliability as a back‑end starter.

Andrew Vaughn continues to deliver a .312/.393/.494 slash line and a 123 Process rating, positioning him as a cornerstone bat for any roster seeking power and on‑base stability.

Meanwhile, Anthony Kay and Sean Manaea have both posted sub‑2.00 ERAs and sub‑1.00 WHIPs this season, making them attractive options for managers looking to solidify the rotation without incurring high acquisition costs.

Finally, Vaughn Grissom’s seven home runs and .251/.320/.393 line illustrate the upside of a player who can contribute both power and speed, a rare blend that often goes unnoticed until late‑season waivers surface.

The ripple effect of these additions is evident across the major fantasy platforms, where the most‑added players are reshaping roster constructions and forcing traditional starter‑centric strategies to adapt.
