Cubs-Orioles Same Game Parlay Options

Given how both teams have looked recently, the Cubs should enter this matchup as the favorites although we are not completely counting out the possibility of the Orioles pulling off an upset win in front of their cheering fans. However, for them to do that, they’ll need the one-two punch of Pete Alonso and Taylor Ward to get going early and force the Cubs’ pitching staff to work from behind.

With the Cubs having so many options offensively, it could prove difficult for the Orioles to shut them down if they can’t establish command early or if the defense starts putting runners on for free. We are expecting Ward to increase his hits tally here but we’re not sure if it would be enough versus a Cubs team that can attack teams on multiple fronts.

That’s why we are steering clear of the Orioles moneyline action here and going for the Dansby Swanson RBI prop instead. The 32-year old shortstop has already tallied 57 RBIs in 84 games played and we don’t see any reason for him to slow down here versus a shaky Orioles defense. That alone should be enough for the Cubs to pull off a dominant win and cover the -1.5 run line here even if we get to see an explosive game from Ward.

Taylor Ward to record 2+ hits
Dansby Swanson to record an RBI
Cubs -1.5
