What happened: The Pittsburgh Pirates' 79-77 record would place them in a virtual tie for a postseason berth if they competed in the American League, according to Jon Morosi. Pittsburgh recently secured a 4-3 final victory over the Kansas City Royals to take a 2-0 series lead.

Why it matters: The contrast illustrates the disparity in win requirements for wild card spots between the two leagues. Pittsburgh remains outside the National League playoff picture despite the winning record.

What to watch: Pittsburgh continues its series against Kansas City.
