The Dodgers have essentially used a six-man rotation all season, with pitchers making just seven starts on four days of rest. Player to watch: With Mookie Betts seemingly mired in seasonlong mediocrity, the Dodgers will need Freddie Freeman to heat up again. He should have two more rehab starts before he's ready to join the rotation -- and the Blue Jays will be counting on him to be in the playoff rotation. After posting a 3.69 ERA in April and 3.17 in May, the rotation ERA rose to 4.52 in June and 4.16 in July, but there are some positive developments. The starting pitching will have to improve, as the Cardinals rank 25th in rotation ERA and 29th in strikeout rate.
