Saturday trading preview
- Cubs to beat Yankees (52%)
- Dodgers to beat Red Sox (61%)
The Yankees and Cubs are battling in what could be a World Series preview as they've been two of the top teams this season. Both teams sit in second place, however, as the Rays lead the AL East and the Brewers lead the NL Central. Both New York and Chicago hold top wild card spots, however, and appear to be top-end contenders as we enter the late stages of the 2026 season. New York won the series opener 2-0 Friday, so the Cubs will try and even things up Saturday. Max Fried (4-3, 3.23 ERA) starts for the Yankees against Chicago's David Peterson (6-7, 5.80 ERA). The SportsLine Projection Model, which simulates every MLB game 10,000 times, has the Cubs winning in 54% of simulations, which is trading at 52% at Polymarket.Â
Another high-profile interleague clash is in the City of Angels with the Dodgers hosting the Red Sox. This series didn't appear to be notable as recently as a few weeks ago, but Boston has been one of baseball's hottest teams and now finds itself holding a playoff spot. The Dodgers, on the other hand, have the best record in baseball and are aiming to win their third straight World Series title. The Red Sox are going for a series win after taking Friday's opener 9-4.  The SportsLine model has the Dodgers winning in the majority of simulations, a result that's priced at 61% on Polymarket. Trade on Saturday's MLB games and more with the Polymarket promo code SPORTSLINE:
