The Cubs and Astros are probably the top two stories in the MLB pennant race this season, but with five weeks still to play, neither has a stranglehold on a playoff spot.
Entering Monday, eight teams were within six games of the American League's final wild card spot.
The Toronto Blue Jays were winners at the trade deadline, but that won't guarantee them an American League East pennant.
If the Cubs make it into the postseason as a wild card team, who will start the one-game playoff: Jon Lester or Jake Arrieta?
If the last four days are any indication, the Cubs are for real.
