What happened: Bradford Doolittle assessed all 30 clubs by post-deadline performance and changes in postseason outlook. Tyler Mahle emerged as the top individual acquisition after five starts with Atlanta.
Why it matters: Atlanta's additions have strengthened an injury-hit rotation during an NL East title chase. The gains produced only a modest change in the club's projected October chances.
By the numbers: Atlanta posted a 108.6 post-deadline rating and a league-best 10.9 pickup-impact mark. Mahle allowed five earned runs in 30 1/3 innings over his first five Braves starts, while the deadline raised Atlanta's postseason odds by 0.3 percentage points.
What to watch: September results will test whether the early returns hold as the playoff race tightens.
