Game 2 sees Colin Rea toe the rubber against Michael McGreevy, and there’s a good chance we see a bunch more runs tonight. That’s because this is a matchup of two struggling starters. Both Rea and McGreevy rank in the Bottom 10% of the league in both expected ERA and opponent expected batting average. The Cubs have been one of the best hitting teams all season, ranking third in wRC+. The Cards, not so much, but the matchup against Rea should be good enough for St. Louis to hit the “Yes” on the Game total Over 8.5 (54%).Yankees (54%) vs. White Sox (47%)TeamPolymarket moneylineEquivalent oddsPolymarket totalNew York Yankees54%-117Over 7.5 (54%)Chicago White Sox47%+113Under 7.5 (47%)The White Sox dropped the opener against the Yankees on Monday night, and things won’t get any easier against Gerrit Cole. After a rough return to the big leagues following Tommy John surgery, the Yankees ace is starting to look like himself again. The right-hander has pitched to a 3.70 ERA and a 0.90 WHIP over four starts this month. He also has great career numbers against the Pale Hose. Current White Sox hitters have combined for a .208 expected batting average and a 32.3% K-rate against Cole. The Yankees have a great chance to win the series tonight.Polymarket vs. Kalshi: How the two prediction markets compareTeamPolymarketKalshiChicago Cubs52%50%St. Louis Cardinals49%50% When it comes to the two major U.S. prediction markets, it’s Polymarket that has the Chicago Cubs as slight favorites while Kalshi has this game as a virtual toss up.
