Monday trading preview

  • Cubs to win, or lose by fewer than 1.5 runs vs. Dodgers (60%)
  • Dream to win vs. Aces (54%)

The Dodgers and Cubs are both contending for the NL pennant this season, and both teams made big pitching additions ahead of the trade deadline. Los Angeles acquired Tigers ace Tarik Skubal, while Chicago made a move for Blue Jays starter Kevin Gausman. Neither will be on the mound on Monday though, as the Dodgers roll with Justin Wrobleski (11-2, 2.88 ERA) and the Cubs give the ball to Matthew Boyd (6-1, 3.41 ERA). The SportsLine Projection Model has the Cubs winning, or losing by fewer than 1.5 runs, in 65% of simulations. That trade is 60% at Polymarket.

The Aces were shocked on Saturday at the buzzer by the Chicago Sky, but they'll have little time to recover from that when they meet a Dream squad that has won five in a row. Angel Reese, who was Atlanta's big acquisition in the offseason, has logged a double-double in four of her last five games and she'll be tangling with MVP frontrunner A'ja Wilson in this one. The Dream are 54% at Polymarket to continue their winning run.
