MLB Trade Deadline Names to Watch Today
The 6 p.m. ET cutoff turns the next few hours into pure theater. Track these MLB storylines:
- Clay Holmes, Mets — one of the best starters left on the market as New York's sell-off continues right into the deadline.
- Mason Miller, Padres — the best closer in baseball, but San Diego's shift to selling clouds his availability.
- Adley Rutschman & Taylor Ward, Orioles — both drawing interest from multiple teams, with Rutschman's odds pegged near 60 percent.
- Angels selling — Los Angeles is expected to deal at least two of pitchers Reid Detmers and Jose Soriano and shortstop Zach Neto before 6 p.m.
- Relief fallbacks — with Miller's status murky, contenders chase arms like Adrián Morejón, Jason Adam, Luke Weaver, and Ryan Zeferjahn.
Each rumor reprices Polymarket contracts live, so the Polymarket promo code ACTION puts real trading funds in your hands the moment news breaks.
Giants vs. Rangers Preview

| Team | Bats to Watch | Arms to Track |
|---|---|---|
| Giants | Rafael Devers, Luis Arraez | Robbie Ray, Landen Roupp |
| Rangers | Josh Jung, Jake Burger | Jacob deGrom, Nathan Eovaldi |
San Francisco leans on Devers' power and Arraez's contact-hitting engine. Texas answers at home with deGrom's electric strikeout stuff and a lineup that punishes mistakes. Trade the moneyline market, live win probability, or player props as the lineups turn over. Use the $20 bonus to cover your first swings.
