Ahead of July 31, teams are circling on frontline arms, middle-order bats, and high-leverage relievers. We break down five names to watch alongside three prospect wildcards.
With the trade deadline looming, contenders are fine-tuning their rosters. MLB.com identifies key names generating buzz: Seth Lugo, the Royals’ reliable righty; Mitch Keller, Pittsburgh’s steady mid-rotation arm; and top-tier arms Sandy Alcantara and Joe Ryan—both in discussion for behemoth trades.
Let’s unpack five standouts who could shift postseason trajectories:
1. Mitch Keller – RHP, Pittsburgh Pirates
-
2025 Stats: 3.48 ERA, 1.143 WHIP, ~2.6 fWAR over 20 starts
-
Why He’s a Target: With strong durability and control, Keller is under team control through 2028, making him a valuable long-term rotation option for teams seeking stability.
The Yankees are “now in the mix” for Mitch Keller according to Noah Hiles of the Pittsburgh Post-Gazette.

2. Sandy Alcantara – RHP, Miami Marlins
-
How He Fits: Fresh off Tommy John surgery, this 2022 Cy Young winner still carries elite upside. Clearing health is key; he’d be a high-reward arm for any buyer.
Sandy Alcántara has a 2.74 ERA in June and will only get better as the year goes on.
The big thing also is he’s not a free agent after this season.

3. Joe Ryan – RHP, Minnesota Twins
-
Why He’s on Radar: Quiet but elite—Ryan posts a 2.72 ERA, 121 K in 109 IP, controlled through 2028. An accurate front-of-rotation arm on many contender wish lists.
Joe Ryan is a great pitcher and immediately slot into one of the top rotation spots for any team.
His ability to get strikeouts and limit walks is one of the best in the league and I’m excited to see if he gets dealt somewhere at the deadline. pic.twitter.com/iMfADwJRgO

Prospect Wildcards
These three emerging talents could sway trade chatter:
-
Sal Stewart – 3B, Reds Triple-A
Slashing well in the minors, he fills multiple corners and DH, in high demand as Cincinnati balances internal promotion vs. the trade market. -
Ke’Bryan Hayes – 3B, Pirates
Gold Glove defender with a pedestrian bat (.238/.284/.293). Still, his contract and defense make him intriguing for teams needing infield depth.

What This Means for Buyers & Sellers
-
Rotation Boosters: Keller, Ryan, and Alcantara offer controlled pitching. Keller is solid value; Ryan is the high-ceiling pickup. Alcantara is health-dependent but high-reward.
-
Offensive Upgrades: Stewart covers internal Reds options.
-
Role Balancers: Lugo and Hayes add veteran stability and defense, respectively—perfect for teams closing in on playoff contention.
As MLB.com observes, these names reflect both buyer urgency and seller timing. Some may fetch top-tier packages; others offer more economical reinforcements.
