Saturday trading preview
- Pirates to win or lose by fewer than 1.5 runs (48%)
- Buccaneers to beat Chiefs (68%)
The Dodgers have started to play better over the last two weeks after a bit of a cold stretch by their lofty standards. They host a Pirates team that's trying to catch a hot streak and climb up the wild card standings. Los Angeles will send prized trade deadline acquisition Tarik Skubal (7-7, 2.85 ERA) to the mound while Pittsburgh will start right-hander Jared Jones (2-5, 4.78 ERA). The SportsLine Projection Model, which simulates every MLB game 10,000 times, has the Pirates winning or losing by fewer than 1.5 runs in more than 60% of simulations, a result that's priced at 48% at Polymarket.
The Buccaneers host the Chiefs in one of the more notable preseason matchups of the week, and they are 68% at Polymarket to win this matchup. The Bucs are expected to have their starters play quite a bit here, including veteran quarterback Baker Mayfield. The Oklahoma product is entering the final year of his contract and will be looking to put together a big season in order to secure a long-term payday with Tampa Bay. The Buccaneers surprisingly didn't win the NFC South last year, so the team is under a lot of pressure to get things right after a late-season collapse in 2025. As for the Chiefs, 2025 was a tough one as the team lost 11 games and missed the playoffs. Additionally, star quarterback Patrick Mahomes tore his ACL late in the season. Mahomes is expected back for Week 1, but he won't play on Saturday. Trade on Saturday's MLB action and more with the Polymarket promo code SPORTSLINE:
