The Cubs have won four in a row since being walked off by the Reds in back-to-back games and they just keep proving to people that they’re a good team. Sweeping the Giants was a huge step toward securing a playoff bid, now the Cubs welcome another postseason contender from the NL West to town for four games.
After a surprise start that saw them leading the division out of the gate, the Diamondbacks have settled in nicely and sit just a half-game behind the Marlins for the third Wild Card spot. Miami has won six straight but just placed ace Sandy Alcántara on the IL, so the D-backs are surely hoping for gravity as well as helium to help them in the standings.
