Rendon went 2-for-3 with an RBI double in Friday's 5-4 victory over the Phillies.
He erased an early 1-0 deficit with a run-scoring two-bagger that plated Daniel Murphy in the fourth, the 26-year-old's ninth RBI over his first eight games in September. Rendon has hit safely in seven of those contests and is slashing .320/.400/.520 over his first 25 at-bats of the new month.
