Yeah, looks like their low point was July 3rd at 39 W - 48 L and thirteen games out of first.
Since then they’ve gone 20 W - 12 L to get back on the doorstep of .500.
Somewhat interestingly, the top five teams in MLB over that stretch have all been the surging NL Wild Card hopefuls - ARI (23-9), CHC (20-12), SDP (19-9), SFG (19-13), NYM (19-14).
