Underdog markets on Friday
Rays vs. Brewers predictions
Jacob Misiorowski (16-5, 1.80 ERA) will get the ball for the Brewers in Game 1 while the Rays will send out Nick Martinez (15-6, 3.10 ERA). The Brewers swept the two-time defending champions Dodgers to reach the World Series, while the Rays won three straight after falling in a 2-1 hole to defeat the Guardians. Neither team has won a World Series before, so MLB will have a new champion. The SportsLine model has the Brewers winning Game 1 in 64% of simulations, and that trade is available on Underdog at 62%.
