Thursday MLB: Two Games to Target
Ten games fill Thursday's July 30 slate, but two matchups stand out for new traders using the Polymarket promo code ACTION.
Nationals vs. Braves — 7 p.m. ET on ESPN. Atlanta hosts Washington in a division matchup that opens the prime-time window. National TV exposure means deep markets and steady price movement, so your $20 bonus stretches across moneyline positions, run totals, and live in-game contracts as the lineups turn over.
Mariners vs. Dodgers — 10:10 p.m. ET on MLB Network. Los Angeles welcomes Seattle in a marquee interleague clash to close the night on the West Coast. This game gives late-night traders a strong second option, and it pairs well with the Braves matchup for anyone spreading the bonus across two games.
As the official prediction market exchange partner of MLB, Polymarket carries game markets for both Nationals vs. Braves and Mariners vs. Dodgers, backed by official league data.
